Your example does not exhibit that behavior when I try it (below). Can you provide a reproducible example following the style shown here:
> Lines <- "a 1 2e-4 + b 2 3e-8" > > DF <- read.table(textConnection(Lines)) > str(DF) 'data.frame': 2 obs. of 3 variables: $ V1: Factor w/ 2 levels "a","b": 1 2 $ V2: int 1 2 $ V3: num 2e-04 3e-08 > R.version.string # Windows XP [1] "R version 2.4.0 (2006-10-03)" On 10/10/06, January Weiner <[EMAIL PROTECTED]> wrote: > Dear all, > > I am having troubles importing values written as scientific notation > using read.table().
