[BioC] Reading SMD data in limma

Hello everyone ... i am trying to make an object from an SMD data
downloaded  from ArrayExpress ... using the limma package .. but
getting this error and the object is not being
created ......
 number of items to replace is not a multiple of replacement length.

The problem appears to be that data files (total 16 files) have
different numbers of rows.  All the files have the same number of rows
(5337 rows), but only the 8th file is different (4993 rows). how these
rows can be made similar in number so that all files can be changed to
a single object.

how can i deal with this situation. if we read files (1-7 & 9-16) and
8 separately  then two objects will be created then how can these two
objects be merged for further analysis.

Please help to sort this problem
