Hi,
I am following the "Example 1: the RepeatMasker Track" given by Michael Lawrence in chapter 5.1 of the documentation for the package 'rtracklayer':
library (rtracklayer)
mySession = browserSession("UCSC")
genome(mySession) <- "hg19"
e2f3.tss.grange <- GRanges("chr6", IRanges(20400587, 20403336))
tbl.rmsk <- getTable(
ucscTableQuery(mySession, track="rmsk",
range=e2f3.tss.grange, table="rmsk"))
Running this code, I get the error message: "error in evaluating the argument 'object' in selecting a method for function 'getTable': error in evaluating the argument 'table' in selecting a method for function '%in%': Unknown track: rmsk"
Listing all available tracks reveals that the name for the track might be: "RepeatMasker".
# List all available tracks in the session
available_tracks <- trackNames(mySession)
print("Available Tracks:")
print(sort(available_tracks))
However, when I replace the track name "rmsk" with "RepeatMasker (see below), I still get an error message:
library (rtracklayer)
mySession = browserSession("UCSC")
genome(mySession) <- "hg19"
e2f3.tss.grange <- GRanges("chr6", IRanges(20400587, 20403336))
tbl.rmsk <- getTable(
ucscTableQuery(mySession, track="RepeatMasker",
range=e2f3.tss.grange, table="rmsk"))
command: tbl.rmsk <- getTable(...) error message: "Error in h(simpleError(msg, call)) : error in evaluating the argument 'x' in selecting a method for function 'as.data.frame': second argument must be a list"
How can I get the example to work?
Kind regards, Andreas
