Dear list, I have a data frame where one of the columns are p values with scientific notation mixed with regular numbers with decimals. >a=data frame >a P OR N 0.50 0.7500 237 0.047 1.1030 237 0.124 0.7742 237 0.124 0.7742 237 0.0080 1.1590 237 0.50 0.7500 237 4.5e-07 1.2 237 5.6e-04 0.9 237
when I try to do >pval=a$P/2 R gives me an error saying "In Ops.factor(pval, 2) : / not meaningful for factors" any help on this? Thank you!
