I followed through the cufflink-cuffdiff-cummerbund pipeline for my analysis involving 2 groups (hyp-has 2 replicate, lyp-only one sample). Everything went well up to cuffdiff but when i tried plotting on cummerbund i end up with error everytime i try to plot (csScatter, csDensity, heatmap) only for the significant genes . Error says that: error:unable to find an inherited method for function 'csScatter' for signature '"data.frame". Im trying to understand where im going wrong, any help will be much appreciated.

Code should be placed in three backticks as shown below

The simplest answer is to point to the error message. The csScatter function doesn't know what to do with a data.frame. But why do you have a data.frame to begin with? There isn't a subset function defined in cummerbund, so when you are subsetting it is likely defaulting to a more general method and not doing the right thing. So ideally you would not use subset and just use your original object.

Also, you are using very old tools. You should upgrade to the current version of R and Bioconductor, as we technically don't support old versions.
