R: prcomp documentation (PR#7372)
I have no idea what you mean by this. prcomp works on a matrix, which has two dimensions, and what you mean by `dimensionality of the data' in PCA depends on whether you are doing R mode or Q mode PCA. Have you read the references on the help page?

help(prcomp) documentation doesn't say that dimensionality of the data treated is number of columns of the matrix. I suggest this to be added somewhere near the description of the matrix argument 'x'.
