Hello R-users,
I'd like to load data from a CSV-file to a 3-dimensional array.
However
the default seems to be 2-dimensional.
No. that is not the problem.
It would also be ok to load the
data and then convert it to a 3-dimensional structure.
I've been trying:
dat = read.csv(filename)
myArr = as.array(dat, dim = c(12,100,3))
However, I get an error message:
Error in `dimnames<-.data.frame`(`*tmp*`, value = list(n)) :
invalid 'dimnames' given for data frame
A dataframe is a list structure while both array and matrix are
expecting the first argument to be an atomic vector. Try this
(although it is a blind guess because you have not provided the
structure of 'dat'
myArr = as.array( unlist(dat), dim = c(12,100,3))

David.
And I don't know how how to set the dimnames.
I would appreciate any help!
Best Wishes
Dave
