Hello,
I am trying to follow ggbio'stutorial, however I am getting errors on the following
1) When plotting the Ideogram, the region does not get highlighted
I am using the following code
p.ideo <- Ideogram(genome = "hg19") p.ideo p.ideo + xlim(GRanges("chr2", IRanges(1e8,1e8+100000)))
I also tried the following, but that also didnthighlight the region
abc <- GRanges("chr1", IRanges(1e8,1e8+10000000)) Ideogram(genome = "hg19", xlabel = TRUE, color = "blue", fill = "green",which = abc)
2) When trying to plot the gene region,
I used the following
library(ggbio) library(Homo.sapiens) class(Homo.sapiens) data(genesymbol, package = "biovizBase") wh <- genesymbol[c("BRCA1", "NBR1")] wh <- range(wh, ignore.strand = TRUE) p.txdb <- autoplot(Homo.sapiens, which = wh)
I get the following error
Parsing transcripts... Parsing exons... Error in `rownames<-`(`*tmp*`, value = c("61241", "61242", "61243", "61244", : invalid rownames length
Any help will be appreciated.
