[R] hist(list)?

[Paul Kienzle]

It seems that the following should work:


> x<-read.table('1A.tab',header=T,skip=1);
> mode(x[1])
[1] "list"
> x[1]
         p01
R1-00 0.0295
R1-01 0.0283
R1-02 0.0145
R1-03 0.0235
R1-04 0.0339
R1-05 0.0239
R1-06 0.0414
R1-07 0.0259
> hist(x[1])
Error: hist: x must be numeric
> as.numeric(x[1])
Error: (list) object cannot be coerced to vector type 14

I've worked around the problem by removing the is.numeric() test from
src/library/base/R/hist.R and in happily produces a histogram for me.
Is there a better way of letting R know that it is working with a list
of numerics only?
