I am going through the XCMS tutorial on the Bioconductor page (https://bioconductor.org/packages/devel/bioc/vignettes/xcms/inst/doc/xcms.html#1_introduction). I get the following error message when I try to plot chromatograms that have been processed (xchromatograms):
Error in (function (cl, name, valueClass) :
‘.processHistory’ is not a slot in class “list”
Referencing back to the tutorial, I start getting errors when I run the code below. Any help is appreciated. Thank you.
sample_colors <- group_colors[xchr$sample_group]
plot(xchr, col = sample_colors,
peakBg = sample_colors[chromPeaks(xchr)[, "column"]])
