R error: could not find function "makeTxDbFromUCSC"

Question

[xiaoleiusc]

Dear All,

I wonder if R stops support for "makeTxDbFromUCSC" function? I tried many times but keep failing with the error message below:

> txDB <- makeTxDbFromUCSC(genome = "hg19", tablename = "ensGene")

Error in makeTxDbFromUCSC(genome = "hg19", tablename = "ensGene") : could not find function "makeTxDbFromUCSC"

Any input is appreciated.

Thanks,

Xiao

Did you load the library?

library(GenomicFeatures)

See possible solutions at SO:

Hi, zx8754, I did not load the GenomicFeatures library, after I loaded it according to your post, I could run the makeTxDbFromUCSC function in R.

I really appreciate your help.

Best,

Xiao
