r - Repeating tk_choose.files to import multiple .csv files multiple times -


i using sapply(tk_choose.files) produce interactive window can choose .csv files (multiple) import. basic data manipulation mean of 1 particular column can plotted using ggplot.

so far code looks this:

>tfiles <- data.frame(sapply(sapply(tk_choose.files(caption="choose t files (hold ctrl select multiple files)"), read.table, header=true, sep=","), c))  >rfiles <- data.frame(sapply(sapply(tk_choose.files(caption="choose r files  (hold ctrl select multiple files)"), read.table, header=true, sep=","), c))

i have calculated mean of particular column both tfiles , rfiles plot 100-tfiles-rfiles.

while working fine 1 set of data, import more sets of data, preferably using sapply(tk_choose.files). need t/rfiles1, t/rfiles2...and repeat data manipulation process after that, plot of multiple sets of data. have no idea how without having copy , paste code!

sorry if stupid question, new r stuck, appreciated!

assuming files in working directory follow:

all.files<-list.files(pattern="\\.csv")  all.files [1] "r01.csv" "r02.csv"  "r03.csv"  "r04.csv" "t01.csv" "t02.csv"  "t03.csv"  "t04.csv"

and wish call tfiles1 merged data of t01 , t02; tfiles2 merged data of t03 , t04

t <- grep("t", all.files, value=t)  t [1] "t01.csv" "t02.csv"  "t03.csv"  "t04.csv"  t.list <- list(t[1:2], t[3:4])  all.t <- lapply(t.list, function(x)ldply(x, read.csv))  (i in 1:length(all.t)) assign(paste0("tfiles", i), all.t[[i]]) #this produce tfiles1 , tfiles2 in r environment.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
