read.cel.intensities {affxparser} | R Documentation |
Reads the intensities of several Affymetrix CEL files (as opposed to
read.cel.complete
which only reads a single file).
read.cel.intensities(fnames, indices = NULL, verbose = 0)
fnames |
the names of the CEL files as a character vector. |
indices |
a vector of which indices should be read. If the argument
is NULL all features will be returned. |
verbose |
an integer: how verbose do we want to be, higher means more verbose. |
The function will initially allocate a matrix with the same memory footprint as the final object.
A matrix with a number of rows equal to the length of the
indices
argument (or the number of features on the entire
chip), and a number of columns equal to the number of files. The
columns are ordered according to the fnames
argument.
Currently this function builds on read.cel.complete
, and simply
calls this function multiple times. If testing yields sufficient
reasons for doing so, it may be re-implemented in C++.

read.cel.complete
for the a discussion of a more
versatile function, particular with details of the indices
argument.
