Dear BioC, I am using siggenes package. If anyone have used, please let me know, how can I get access of all samoutput$fdr and samoutput$delta values from samoutput object? This might be very easy..but and even I have also opened Vignette but there is not information in Vignette as well.(sam.out$mat.fdr gives NULL) I did following: > samoutput <- sam(MatrixRMA,cl, rand = 123); We're doing 90 complete permutations >samoutput$mat.fdr NULL > samoutput SAM Analysis for the Multi-Class Case with 3 Classes Delta p0 False Called FDR 1 0.1 0.854 408.578 426 0.819 2 259.8 0.854 4.400 14 0.268 3 519.5 0.854 1.733 6 0.247 4 779.2 0.854 0.722 3 0.205 5 1038.9 0.854 0.333 2 0.142 6 1298.6 0.854 0.333 2 0.142 7 1558.3 0.854 0.333 2 0.142 8 1818.0 0.854 0.111 1 0.095 9 2077.7 0.854 0.111 1 0.095 10 2337.5 0.854 0.000 0 0.000 >summary(samoutput) SAM Analysis for the Multi-Class Case with 3 Classes s0 = 0.0048 (The 5 % quantile of the s values.)

The following commands are very helpful: names(object) lists all the components in the object. class(object) gives the classname(s) such as SAMout or whatever. Then ?SAMout usually says what is in the object. --Naomi At 08:04 AM 12/22/2005, Sean Davis wrote: >On 12/22/05 7:53 AM, "Saurin Jani" <saurin_jani at="" yahoo.com=""> wrote: > > > Dear BioC, > > > > I am using siggenes package.
