Hello, I used plotPCA function in DESeq2.

Thanks in advance for great help!

Best,

Yue

vsd is supposed to be a DESeqTransform object. From the manual:

a DESeqTransform object, with data in assay(x), produced for example by either rlog or varianceStabilizingTransformation.

So, something like:

vsd <- varianceStabilizingTransformation(dds)
plotPCA(vsd, intgroup=c("condition"))

I guess the function is masked by any package for microarray analysis because it tries to call exprs() on vsd.

Could be - moved back to comment. plotPCA is overloaded between DESeq2 and affycoretools

One note (more for developers than users) is that if a method masks plotPCA or other function names that are listed as generics here, they can avoid this by exporting a method for those generics.

Try to avoid loading DESeq. This version is official deprecated.

Try DESeq2::plotPCA(vsd, intgroup=c("condition"))

It's not necessary to specify an S4 function using the double colon, so long as there isn't an object dispatch clash (which there isn't in the case of DESeq2 and affycoretools).

> library(DESeq2)
> library(affycoretools)

I did not say it was that particular package, but there is a conflict here since plotPCA (from whatever package it comes) tries to call exprs() on the input object, right?

ADD REPLY •

True. You only said it was a microarray analysis package. Kevin Blighe said it was affycoretools that overloaded DESeq2, which isn't a thing, since both packages use the method defined by BiocGenerics and export correctly.

It's either another package that has a bare or S3 function, or perhaps the OP wrote their own? Anyway, without the output from sessionInfo it's not possible to say.

Was the effect of responding in haste while trying to do all of my 1 million jobs. plotPCA() is actually used in many different packages, it seems. Won't know much more until user gets back (currently middle of the night in China).

Yes, and me going all 'Grrr, talking smack about my package, are ya!' probably without warrant. ;-D

You need to supply the results from 

sessionInfo()

What you have supplied is the function body, which you get by doing


sessionInfo

Which is a different thing.

ADD REPLY •

You could also do

plotPCA

Which will give the function body, and where it comes from, which would be pretty helpful as well.

Hello James W. MacDonald, Thank you so much for your great help! I have already added these information.

Thank you again! Best, Yue

You seem to have too many packages open in the same workspace. Do you really need all of these in the same workflow:

affycoretools              DESeq       
tximeta     DESeq2
tximportData  tximport
limma

You should close your workspace when not using it, and only load packages that you need. For example, there is no major reason why you should have DESeq and DESeq2 loaded together (DESeq is also being deprecated, as per Michael's comment above).

Be selective in the packages that you load, and close your workspace when not using it. One can run into all sorts of problems by leaving packages loaded and old variables in the same workspace.
