有这么一段话，跟你case很像
5. Read in the data and create an expression, using RMA for example.
R> Data <- ReadAffy() ##read data in working directory
R> eset <- rma(Data)
Depending on the size of your dataset and on the memory available to
your system, you might experience errors like 'Cannot allocate vector
. . . '. An obvious option is to increase the memory available to your
R process (by adding memory and/or closing external applications2 . An
another option is to use the function justRMA.
R> eset <- justRMA()
This reads the data and performs the 'RMA' way to preprocess them at
the C level.
One does not need to call ReadAffy, probe level data is never stored
in an AffyBatch. rma continues to be the recommended function for
computing RMA.
可是你是第一个命令就报错了，我估计你没法用justRMA()了。。。
