Hi, I was trying the code in the reference manual to get the GC content but it's giving errors. All the parameters appear to be correct (I checked with UCSC) - here is the code, as given in the manual: ############### from <- 65921878 to <- 65980988 gcContent <- UcscTrack(genome = "mm9", chromosome = "chrX",    track = "GC Percent", table = "gc5Base", from = from,          to = to, trackType = "DataTrack", start = "start", end = "end", data = "score",          type = "hist", window = -1, windowSize = 1500, fill.histogram = "black",          "darkblue",col.histogram = "black", ylim = c(30, 70), name = "GC Percent") ############## The errors that I get: Error in UcscTrack(genome = "mm9", chromosome = "chrX", track = "GC Percent",  :   Error fetching data from UCSC In addition: Warning message: In UcscTrack(genome = "mm9", chromosome = "chrX", track = "GC Percent",  :   Error in try(track(query), silent = TRUE) :   could not find function "track" thanks!!
