This might be obvious but I was wondering if anyone knows quick and easy way of writing out a CSV file with varying row lengths, ideally an initial data read from a CSV file which has the same format. See example below.
I found it quite strange that R cannot write it in one go, so one must append blocks or post-process the file, is this true? (even Ruby can do it!!) Otherwise it puts ,"","" or similar for missing column values in the shorter length rows and fill=FALSE option do not work! I don't want to post-process if possible. See this post: http://r.789695.n4.nabble.com/Re-read-csv-trap-td3301924.html Example that generated Error! writeLines(c("A,B,C,D", "1,a,b,c", "2,f,g,c", "3,a,i,j", "4,a,b,c", "5,d,e,f", "6,g,h,i,j,k,l,m,n"), con=file("test.csv")) read.csv("test.csv") try(read.csv("test.csv",fill=FALSE)) LEGAL NOTICE This message is intended for the use o...{{dropped:10}} ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
