Hi to everybody, i have a problem with 2 expressionsets: > pData(eset.1) sample WK-PUFA3.CEL 5 WK-PUFA4.CEL 6 WK-st1.CEL 7 WK-st2.CEL 8 and: > pData(eset2) sample SHR-PUFA5.CEL 1 SHR-PUFA6.CEL 2 SHR-st7.CEL 3 SHR-st8.CEL 4 i would like to obtain only one dataset that included this two, so i would like to obtain something like this: > pData(data.rma) sample SHR-PUFA5.CEL 1 SHR-PUFA6.CEL 2 SHR-st7.CEL 3 SHR-st8.CEL 4 WK-PUFA3.CEL 5 WK-PUFA4.CEL 6 WK-st1.CEL 7 WK-st2.CEL 8 best regards. -- ----------------------------------------------------- Dr. Alberto Goldoni Bologna, Italy ----------------------------------------------------- [[alternative HTML version deleted]]

Hello, please have a look at the 'combine' method from the Biobase package. Try D <- combine(eset2, eset.1) If that does not work for you, please provide the detailed error message and the output of function sessionInfo().
