Hi~ helpers.

I was surprised by R data type.

I use to data type like table.

I don't know R allow several data type such as list, number, matrix in the
same matrix.

I want to use plsr in pls package to anlaysis data.

So, I read R help and example of plsr.

that example show me that data as yarn has three colname as NIR, density and
train.

the NIR was 268(No. of col) X 71(No. of row) matrix, but  density was just
71 list

yarn[1] indicate NIR, and yarn[2] indicate density

so I just tested like that TEST=c(matrix , list)

But It was wrong.

how can I make like matrix?

Of cource, the python, perl or JAVA could like that.

just simplely but  I don't know in R.

please tell me about that.
