[R] R help

[Jeff Newmiller]

In general you should read the Posting Guide mentioned at the bottom of every email, which points out that you should post in plain text. Figuring out how to send plain text email in your email client will help you make sure that we see what you see. 

You should also try to insert reproducible code in your email rather than isolated snippets. Read the discussion at [1] to learn more.

filter(df, grepl( "\\.002", as.character( Number ) ) )

If you import the data with the stringsAsFactors=TRUE option you could get rid of the as.character conversion.  You should also look at the help for %in% because it compares the whole string, not sub strings.

?"%in%"
