I have been having trouble of running UcscTrack() in the package "Gviz" to make DMR plot.
My methylation data is using GRCh37/hg19 genome. ( whole blood tissue )
I have been following the online guide of making DMR plot : https://github.com/hansenlab/tutorial.450k/blob/master/vignettes/methylation450k.Rmd
Please see the code I used and the error I got from R as below:
# include your problematic code here with any corresponding output # please also include the results of running the following in an R session rTrack <- UcscTrack(genome = genome, chromosome = chrom, track = "refGene", from = minbase, to = maxbase, trackType = "GeneRegionTrack", rstarts = "exonStarts", rends = "exonEnds", gene = "name", symbol = "name2", transcript = "name", strand = "strand", fill = "darkblue", stacking = "squish", name = "RefSeq", showId = TRUE, geneSymbol = TRUE)
R keeps giving me the error like this:
I would really appreciate it if anyone would love to provide some suggestions or solutions. This is my first time of writing a post here, so sorry about the confusion if there's any.
Thank you very much!
