[R] Histogram

[Andrew Robinson]

x is not a numeric vector, so R doesn't know how to take a histogram.
Here are your clues:

> class(x)
> [1] "data.frame"
> is.numeric(x)
> [1] FALSE

so, try

names(x)

I speculate that LOGT is contained in the dataframe x.  If so, try

hist(x$LOGT)

I hope that this helps.
