Re: [R] Question about error of non-numeric argument to binary operator
Thanks, Marc,
I tried it and it didn't really work.
x.num-as.numeric(x)
is.numeric(x.num)
[1] TRUE
x.num-readClipboard()
is.numeric(x.num)
[1] FALSE
is.character(x.num)
[1] TRUE
I use readClipboard to take in data, and it seems after the data is taken
in, x.num changed to character.
I just start using R, not familiar with the data import/export
functions...besides of that, I have a question about read.table, can this
function read in spreadsheet data? if so, is the excel file supposed to put
in the same directory with the R-2.4.0 folder?? Which is what I did, but I
got the following error
read.table(bra5y.xls,header = TRUE, row.names = 2)
Error in read.table(bra5y.xls, header = TRUE, row.names = 2) :
object bra5y.xls not found
Pls help.
Thanks!

Your 'x' is a character vector, not numeric. The tip is that the values
are surrounded by double quotes. Thus, you are trying to use operators
intended for numerics on characters.
For example:
x - c(122, 126.5, 136, 148, 147, 150.5, 143.5)
x
[1] 122 126.5 136 148 147 150.5 143.5
x / 1
Error in x/1 : non-numeric argument to binary operator
is.numeric(x)
[1] FALSE
is.character(x)
[1] TRUE
It's not clear from your post how you read in the data originally. You
should review that process or alternatively, coerce 'x' to numeric:
x.num - as.numeric(x)
x.num
[1] 122.0 126.5 136.0 148.0 147.0 150.5 143.5
x.num / 1
[1] 122.0 126.5 136.0 148.0 147.0 150.5 143.5

Re: [R] Question about error of non-numeric argument to binary operator
Yulei, It would appear that the default mechanism for the function (which appears to be Windows specific) is to read in the data from the current system clipboard as a _character vector_. Thus, perhaps something like: x.num - as.numeric(readClipboard()) would be helpful. With respect to reading in Excel files, you cannot directly import Excel files using read.table() and friends. You can export from Excel to an ASCII delimited file and then use these functions. Alternatively, there is the read.xls() function in the 'gdata' CRAN package, which can directly read such files. I would strongly advise reviewing the R Import/Export Manual, which is available from the menus in the Windows GUI, as it will provide guidance in this area.

Re: [R] Question about error of non-numeric argument to binary operator
Marc, Thanks! x.num - as.numeric(readClipboard()) works perfect. Meanwhile, I have tried to use odbcConnectExcel from RODBC pack. It seems to work as well. I am able to read in the data, but I need to construct a sql table from the data, and use sqlFetch to retrieve and assign them to variable. More steps.
