Error: Unexpected symbol in "1M"

This has nothing to do with finance, so you should have posted it to R-help instead. The answer to your question is found in "An Introduction to R", section 1.8: R commands, case sensitivity, etc. "... a name must start with '.' or a letter, and if it starts with '.' the second character must not be a digit." Technically, you can assign a value to a name that starts with a number, but you will run into lots of problems.

Hi R users:
I tried the following coding:
COMPdata <- read.csv("D:/........./Book1.csv", header=TRUE, sep=",")
INDEX <- COMPdata[, 1]
1M <- COMPdata[, 2]
2M <- COMPdata[, 3]
The partial list of original data Book1.csv is listed below:
INDEX 1M 2M 3M 4M
1 0.0001026472 0.0001026472 0.0001427507 0.0001026147
2 0.0001026109 0.0001026109 0.0001453323 0.0001029040
3 0.0001169544 0.0001169544 0.0001326488 0.0001070135
4 0.0001159930 0.0001159930 0.0001362505 0.0001048737
5 0.0001212301 0.0001212301 0.0001320264 0.0001139550
6 0.0001211852 0.0001211852 0.0001247280 0.0001137742
The dataset read-in looks fine:
head(COMPdata)
INDEX X1M X2M X3M X4M 1 1 0.0001026472 0.0001026472 0.0001427507 0.0001026147 2 2 0.0001026109 0.0001026109 0.0001453323 0.0001029040 3 3 0.0001169544 0.0001169544 0.0001326488 0.0001070135 4 4 0.0001159930 0.0001159930 0.0001362505 0.0001048737 5 5 0.0001212301 0.0001212301 0.0001320264 0.0001139550 6 6 0.0001211852 0.0001211852 0.0001247280 0.0001137742 Nothing wrong with the first column:
INDEX <- COMPdata[, 1]
However, it gives me the error message below
1M <- COMPdata[, 2]
Error: Unexpected symbol in "1M"
So do the other variables 2M, 3M, and 4M.
Could some people share advice to solve this problem?
Thanks for your kind attention.
