Read in alphanumeric column without decimals
Your problem is the the data read in from the spreadsheet is probably a 'factor' since it has a non-numeric in the column. To change it to number you have to do the following as.numeric(as.character(yourdata$TeamLeaderID)) What you as seeing with just the call to as.numeric is the value of the 'factor', not the value of the number.

How can I read in a column of alphanumeric values without including
".0" on the numeric values?
Original column:
TeamLeaderID
258
342
316
U8
331
279
D1
116
235
296
...
[truncated]
leaders = read.xlsx2('FILE', sheetIndex = 1, header = T)
Column after it's been read in:
leaders$TeamLeaderID
258.0
342.0
316.0
U8
331.0
279.0
D1
116.0
235.0
296.0
...

If I try
as.numeric(leaders$TeamLeaderID), everything gets converted:
leaders$TeamLeaderID
11
27
19
54
23
13
28
2
8
15
...
[truncated]
as.character() and as.vector() leave the ".0" in place.
These data are being used to merge two files, one whose
data$TeamLeaderID is identical to the original column of values above.
When I try to merge the dataframes by "TeamLeaderID," R can't match
the numbers without decimal to the ones that have decimal points. The
alphanumeric TeamLeaderID values merge without a problem. As a
result, I get a dataframe filled with the proper values for those
TeamLeaderID values that are alphanumeric, but "NA" values for those
whose values are strictly numeric.
How can I read in the values without R adding the ".0" to the end of
the numerals? If there isn't a way, how can I automate the removal of
the ".0," as I have several 10s of TeamLeaderID values?
I'm using 64-bit R v. 2.15.1 on a Windows 7 machine.
Thank you -
