First I converted the .plt file to a .txt file then I imported in R.
But when I try to read the text file, I get an error:
`20081023025304` <- read.t
You need to skip 7 lines before reading your data. Also, the separator is ,. So you need something like
,
read.table("file.plt", header = TRUE, quote = "\"", skip = 7, sep = ",")
