I am trying to use the ballgown Plotmeans function to display side-by-side plots of transcript level expression under 3 different experimental conditions (3 conditions with only 2 replicates per condition).

I am using the following code:

plotMeans("MSTRG.8",bg_data_filt,groupvar = "Condition", groupname = "all",  meas = "FPKM", colorby = "transcript")

but only getting 1 plot (the first displayed) in R-Studio. No error message is shown.

I have used the plotTranscripts function and that seems to display my 6 samples side-by-side with no problem:

plotTranscripts(gene = 'MSTRG.8',bg_data_filt, samples=c("1a","1b","2a","2b","3a","3b"), meas = 'FPKM', colorby = 'transcript', labelTranscripts = TRUE)

Can anybody offer any suggestions as to why plotMeans isn't working as intended?

Just checked and increasing replicate number to 3 allows plotting of means. I am assuming this is some hard coded limitation of ballgown. If anyone else is finding this and could comment just to confirm that would be appreciated.
