Dear R users, I want to read a file like following : if it is a table then z <- read.table(pathname, dec=".", header=TRUE) else if it's not a table (image,doc,...) then send an error or something like that
acually I have a read.table in the beginnig of my R code, and if my data is not a table I become in my R console : fail in scan. So the question is how to check the nature of the file? something like : is.table? I don't know the function. Thanks for any help Adel -- View this message in context: http://www.nabble.com/read-and-check-table-tp18532292p18532292.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
