Tidyverse masking Genefilter after BioConductor update
Entering edit mode
Last seen 12 months ago

Dear Friends,

Recently I updated to BioConductor v3.7 and the library for IlluminaHumanMethylationEPICanno.ilm10b4.hg19.  I was running R 3.4.4 at the time and started to have problems with several packages after accessing the library for EPIC anno b4.  I have now updated R to 3.5.1 and am experiencing a variety of problems.  Tidyverse has different conflicts each day.  Today's conflicts are greater than usual, so it must be Monday. 

One issue that concerns me is that after sorting out all these R package updates, my results are very different from when I ran EPICanno version b2.  My results now show adjusted p-values that are all 1, despite the p values being different for each probe.

I am running Windows 10 but had a similar problem with Tidyverse conflicts on a Mac with OS High Sierra.

Thank you for any suggestions.

Well, you have the exact same logFC and average expression for the first probe in both comparisons, but the t-statistic is almost cut in half. The code you show indicates that you used treat for at least one of these examples. But you couldn't have used treat for the first example since the default logFC is log2(1.2), which is 0.263. Since you have probes with a logFC smaller than that in your first example, you can't have used treat to get those results. So you made changes to your code between those examples, which probably explains the differences you see.

Thank you James for your comments.  I did use "treat" in both analyses.  I ran them again on my colleague's computer and the results were in line with earlier runs with version b2  (IlluminaHumanMethylationEPICanno.ilm10b2.hg19).  I only called dplyr from the Tidyverse but perhaps a package is still being masked when I run limma.

There are two issues here. First, you have conflicts between function names. The easy way around that is to always use the fully qualified function name (e.g., Package::function), so for example if you need to use the collapse function from Biostrings, you call Biostrings::collapse, which will ensure that you get that one rather than the collapse function that is highest on the call stack. You might also consider not loading the tidyverse, but rather loading individual packages that are part of the tidyverse that you might need.

The second issue is that you say your results have changed, without giving any way for people to try to diagnose. Just saying that you get different results, without giving any code, or ideally a self-contained example that shows the differences is not nearly enough information for anybody to even make an attempt to try to help.

Thank you James for your suggestion to just load the packages of Tidyverse that I need.  What I consider as a problem with my results was the p-values and the adjusted p-values.  Please see the two tables below.

Using the limma package.  Here is a bit of my script.

mod = model.matrix(~ 0 + AP1 + factor(Gender) + factor(smoker), data = target)

colnames(mod) <-gsub("AP1","",colnames(mod))
colnames(mod) <- make.names(colnames(mod))

contrast.matrix <- makeContrasts(Olanzapine = Ola-(Ari+Que)/2, levels = mod)

## fit model####
fit = lmFit(data, mod)
fitContrasts <- contrasts.fit(fit,contrasts=contrast.matrix)
eb = treat(fitContrasts)
results = topTreat(eb,adjust="fdr",number=length(eb$coefficients))
