i importing survey data csv file in r, , want use for-loop reassign periods in cells "na". 1 survey item, have this: survey$q1a <- recode(survey$q1a, "'.'=na") # csv column survey$q1a <- as.numeric(as.character(survey$q1a)) where q1a column title in csv file, , refers question 1, part (i have 137 columns). so, in order make for-loop, need able this: for (n in 1:31){ survey$qna <- recode(survey$qna, "'.'=na") # csv column n survey$qna <- as.numeric(as.character(survey$qna)) } 31 items have part a, means need survey$q1a survey$q31a . sake of simplicity, best keep columns in qna format (ironically). have never used r, have experience python , c, , know use % %s operators in languages achieve similar goals. is there way in r without changing how variable/column labeling system?

i have been utilizing pca implemented in scikit-learn. however, want find eigenvalues , eigenvectors result after fit training dataset. there no mention of both in docs. secondly, can these eigenvalues , eigenvectors utilized features classification purposes? i assuming here eigenvectors mean eigenvectors of covariance matrix. lets have n data points in p-dimensional space, , x p x n matrix of points directions of principal components eigenvectors of covariance matrix xx t . can obtain directions of these eigenvectors sklearn accessing components_ attribute of pca object. can done follows: from sklearn.decomposition import pca import numpy np x = np.array([[-1, -1], [-2, -1], [-3, -2], [1, 1], [2, 1], [3, 2]]) pca = pca() pca.fit(x) print pca.components_ this gives output [[ 0.83849224 0.54491354] [ 0.54491354 -0.83849224]] where every row principal component in p-dimensional space (2 in toy example). each of these rows eigenvector of centered covariance mat

i trying create functional tests using selenium (on django / python), javascript file validation brings error. site takes csv file input , presents bunch of graphics visualize csv data in different ways. using jquery validation plugin check csv file via 1) extension .csv, , 2) mime-type text/*. this validates fine manually when upload .csv file, when try upload same file in selenium, mime-type error. there way "set" file input's mime-type, or should have that? missing file uploading in selenium? know i'm not supposed click file button , sending full path using send_keys(). i haven't found similar questions on or google. every selenium mime-type question deals downloading files during test, instead of uploading files. thanks help! my selenium test code: file_input = self.browser.find_element_by_id('grade_file') file_input.send_keys('/<fullpath>/grades_deid.csv') grade_form = self.browser.find_element_by_tag_name('form')

i'm trying understand given algorithm , here thoughts: a given array... x stands number on left side of pivot element, y stands number on right side of pivot element. (let's pivot element element on right side of array.) , a[y] stands pivot element? if understood correctly, algorithm first searches x towards y until first number greater or equal a[y] , search y towards x until first number smaller or equal a[y] . after, swap both numbers , repeat if i hasn't reached j . in end numbers left i smaller a[y] , numbers right j larger a[y] ... move a[y] middle. think this? right? maybe give example random array? cannot yet believe. algorithm quicksort 1 func int div (a array; x, y integer) { 2 num = a[y]; 3 = x; 4 j = y-1; 5 repeat 6 while (a[i] <= num , < y) 7 = i+1; 8 end while; 9 while (a[j] >= num , j > x) 10 j = j-1; 11 end while; 12 if < j 13 swap (a[i], a[j]); 14 en

so have joomla site , in joomla documentation can't find mysql's if, else function within query. the part of query need if statement in mysql here. $query->where($db->quotename('container').' != 1'); it should doing : $query->where('if '.$db->quotename('server_number').' != '.$number.' '$query->where($db->quotename('container').' != 1');' end'); if $number input not match server_number column data add statement mysql query. full mysql query : select a.*,ext.media_type database_hwdms_processes left join database_hwdms_media media on media.id = a.media_id left join database_hwdms_ext ext on ext.id = media.ext_id (a.status = 1 || a.status = 3) , a.attempts < 5 , `container` != 1 , server = 1 order a.media_id asc want add "if server_number != 1 container != 1 end" mean replacing "and container != 1" i figured out better way resolve problem

i'm trying find items have shown 1 time or less on report. know find how many times each item has apepared, use this. select count(vp.vendorpartid) purchasing.purchaseorder po (nolock) inner join dbo.tblvendor v (nolock) on po.vendorid=v.vendorid inner join purchasing.purchaseorderitem poi (nolock) on po.purchaseorderid=poi.purchaseorderid inner join purchasing.vendorpart vp (nolock) on poi.vendorpartid=vp.vendorpartid v.producttypeid=4 group po.purchaseorderid but tried nest within query able set must appear 1 time or less, , says there's error because "subquery returned more 1 value. not permitted when subquery follows =, !=, <, <= , >, >= or when subquery used expression." i did this, i'm guessing pretty wrong, haha. select vp.vendorpartid,vp.vendorpartdescription purchasing.purchaseorder po (nolock) inner join dbo.tblvendor v (nolock) on po.vendorid=v.vendorid inner join purc

hey have problem placing variables. how can use variables use lets in function "a" in function "b". in word use variables function "a" in function "b" i have function("a") set notification text: let sentence = textfield.text! + " beautiful text!" let firstword = sentence.characters.split(" ").first.map(string.init) localnotificationhelper.sharedinstance().schedulenotificationwithkey("sometext", title: "see options(left)", message: sentence, date: deadlinepicker.date, userinfo: userinfo) now gotta call firstword inside function("b") in variable here: let predicate = cncontact.predicateforcontactsmatchingname(firstword) i tried add first variables sentence , firstword in viewdidload , outside of class nothing. keep getting error "found nil while unwrapping" call function variable predicate when user tap notification action button this. nsnotificationcenter
