Hi Martin,
I am not sure who I should contact with for this problem. I just send this
to you. The problem is: when I try to combine two numeric types (integer and
double) of matrix (actually they are in the assayData of ExpressionSet), the
combine function reports error. For example:
a = matrix(rnorm(10), 2)
# set rownames and colnames because combine function require it.
colnames(a) = LETTERS[1:5]; rownames(a) = 1:2
b = matrix(1:10, 2)
colnames(b) = LETTERS[6:10]; rownames(b) = 1:2
combine(a, b)
> Error in combine(a, b) : matrix types double, integer differ
I suppose the combine function should automatically convert the integer as
double before combining them because this situation can be met very often.
What's your suggestion? Thanks!
Have a nice day!
Pan
