This program works because I made the varibles inisde lapply global by using the <<- operator. However, it does not work with the real files in the real program. These are .tsv files whith named columns. The answer I get when I run the real program is: Error: (converted from warning) Error in : (converted from warning) Error in : arguments imply differing number of rows: 3455, 4319. What might be causing this?
lc <- list("test.txt", "test.txt", "test.txt", "test.txt")
lc1 <- list("test.txt", "test.txt", "test.txt")
lc2 <- list("test.txt", "test.txt")
#list of lists. The lists contain file names
lc <- list(lc, lc1, lc2)
#new names for the three lists in the list of lists
new_dataFns <- list("name1", "name2", "name3")
file_paths <- NULL
new_path <- NULL
#add the file names to the path and read and merge the contents of each list in the list of lists
lapply(
lc,
function(lc) {
filenames <- file.path(getwd(), lc)
dataList <<- lapply(filenames, function (lc) read.table(file=lc, header=TRUE))
dataList <<- lapply(dataList, function(dataList) {merge(as.data.frame(dataList),as.data.frame(dataList))})
}
)
#add the new name of the file to the path total will be 3 paths/fille_newname.tsv.
lapply(new_dataFns, function(new_dataFns) {new_path <<- file.path(getwd(), new_dataFns)})
finalFiles <- merge(as.data.frame(dataList), as.data.frame(new_path))
print(finalFiles)
