Hi,

I would like to install an old version of Affy package in R.

I tried to download the package and install but i am getting error as :

"Error : object '@<-' is not exported by 'namespace:methods'
ERROR: lazy loading failed for package 'affy'"

I have used the following command to install this package:

R CMD INSTALL -l ../packages/ affy_1.36.1.tar.gz

Please let me know what the issue is, also how can i install affy package 1.36.1 in R-3.2.2

Regards,

JK

Bioconductor packages are designed to work with specific versions of R and other packages. affy 1.36.1 is from Bioconductor version 2.11, which uses R version 2.15 and is from October, 2012. This is a very long time ago in the R / Bioconductor world.

If this is really what you want to do, then you'll need to install R 2.15 available from the R project pages. The standard source("http://bioconductor.org/biocLite.R"); biocLite("affy") should install the correct version of Bioconductor packages; it may be that there is significant extra work to install the correct CRAN package versions.
