Hello,
A am creating a subset of data from a data matrix as follows:
theSubset=theData[theData$Fieldname=="A string",]
For some reason, a row of "NA" values is inserted into theSubset, screwing up the statistics I want to do on that subset of data. I can't figure out why it is doing this. There are no "NA" values in the field that I am using to subset the data. The data set was imported from an Excel spreadsheet.
Any help would be appreciated.
Thanks,
