pathview R package not working

Question

[catechize.2.learn]

Hi!

I cannot make any useful plots in pathviews. Where am I going wrong?

library(pathview)
a= c( -2,4)
names(a) =c('MDM2', 'TP53')
pathview(gene.data = a, pathway.id = "04115", species = "hsa")

there is no highlighting of either p53 or mdm2 in the resulting fig.

I think the answers is on the warnings you get:

Warning: None of the genes or compounds mapped to the pathway!
Argument gene.idtype or cpd.idtype may be wrong.

You can't use the gene names (symbols), but have to use ENTREZ gene IDs.

library(pathview)
a= c( -2,4)
names(a) =c("4193", "7157")
pathview(gene.data = a, pathway.id = "04115", species = "hsa")

To get these entrez IDs you can use org.Hs.eg.db in R.

library(org.Hs.eg.db)
symbols = c("MDM2","TP53") 
names(a) <- mget(symbols, revmap(org.Hs.egSYMBOL),ifnotfound=NA)
