Joshua, Dennis ans Henrique I'm immensely indebted to you. Thanks to you I resolved my problem - a code works perfectly. I put the code, maybe someone finds it's helpful.
f1 <- readLines(file("file1.txt")) f2 <- readLines(file("file2.txt")) for ( i in seq_along(f1)){ assign(f1[i],as.numeric(unlist(strsplit(f2[i],",")) )) } file 1 (names of the variables; just copy and paste to see how it works) A A2 A3 A4 A7 B B4 B5 B7 C C1 C3 C4 C6 F D file 2 (values of the variables; just copy and paste to see how it works as well) 1 3, 6, 7 4, 13, 9 5, 2 8,10, 11,12,15 17 21, 29, 18, 32, 145 22, 34, 19, 27, 20 24, 23, 33, 28, 25, 26 35 36, 40 38, 37 39 41 92 42 Robert ______________________________________________ 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.
