I do not think so. Probably separation character of your file is not "," as you set in sep=",".

e.g. ID.JURIS.RESCODE was read into one column.

Best way how to copy data from Excel (if you have Excel)

Select your data in Excel including first row with headers Ctrl-C
Go to R
Write mydata <- read.delim("clipboard")

or look at JACSdata2.txt what is the separator between fields and set it in your read.table command accordingly. From later I suppose your txt file is tab delimited so
read.delim(....)
shall capture it.
