Hi all,
I'm using the GOstats package to find significant GO terms. This has
been
working fine but I've just upgraded to the R version 2.7.2 (and the
latest
versions of the Bioconductor packages) and I now get an error. I've
had no luck
trying to fix this and so am hoping someone an help me!
EXAMPLE CODE:
library(GO.db);
library(GOstats);
library(ath1121501.db);
geneIDs <-
c("AT1G21670","AT4G19960","AT5G37600","AT1G56220","AT1G53310")
params <- new("GOHyperGParams", geneIds=geneIDs,
annotation="ath1121501.db",
ontology='MF', pvalueCutoff=0.05, conditional=TRUE,
testDirection = "over");
hgTestResult <- hyperGTest(params);
WHICH PRODUCES AN ERROR WHEN RUNNING THE "hyperGTest" FUNCTION:
Error in get(mapName, envir = pkgEnv, inherits = FALSE) :
variable "ath1121501ENTREZID" was not found
Error in mget(probes, ID2EntrezID(datPkg)) :
error in evaluating the argument 'envir' in selecting a method for
function
'mget'
TRACEBACK
14: mget(probes, ID2EntrezID(datPkg))
13: unlist(mget(probes, ID2EntrezID(datPkg)))
12: unique(unlist(mget(probes, ID2EntrezID(datPkg))))
11: getUniverseHelper(probes, datPkg, entrezIds)
10: getUniverseViaGo(p)
9: universeBuilder(p)
8: universeBuilder(p)
7: is(object, Cl)
6: is(object, Cl)
5: .valueClassTest(standardGeneric("hyperGTest"), "HyperGResultBase",
"hyperGTest")
4: hyperGTest(params)
