Which means it avoided converting to factor... Success! Note that the column apparently has garbage characters in one or more of the rows, which should be evident when you LOOK AT THE CHARACTERS in the column. They should all be numeric symbols, plus or minus, and perhaps decimal points. If they are not, then the conversion to numeric will be incomplete. See my other message. You have the choice of editing the file (may have concerns with traceability), or you can write R code that removes the garbage characters using gsub. -- Sent from my phone. Please excuse my brevity.

Thanks. The former method works. I confused character with factor. Besides, I should use: dta$DischargeNum <- as.numeric( dta$Discharge ) instead of: dta$Discharge <- as.numeric( dta$Discharge ) On Tue, Sep 20, 2016 at 5:18 PM, Jeff Newmiller <jdnewmil at dcn.davis.ca.us> wrote:> Which means it avoided converting to factor...

You can use the latter IF you know there are no problems with the input data. If you need to troubleshoot then you need separate columns so you can compare them. -- Sent from my phone.
