Hi,

I just started using R and am having trouble with the below error:

I type:

> df <- read.csv("/home/rex/Desktop/mytable.csv")

which gives me what I want:

...
639 2006-05-26 16:46:54     4   16
640 2006-05-26 17:05:36     5   17
641 2006-05-26 17:30:48     6   17

But now I try:

> plot(df[4],df[3])
Error in pmatch(x, table, duplicates.ok) :
        argument is not of mode character

Any ideas? I tried read.table and importing the data from MySQL too; same
error.

Thanks,

Rex
