I am tryibng to use xval to run KNNB on an exprSet object. Trying to
run down the source of my difficulties I went to the xval help file
and executed the example shown below (also found in the xval help
file).
> library(golubEsets)
> data(Golub_Merge)
> smallG<-Golub_Merge[200:250,]
> lk1<-xval(smallG, 'ALL.AML', knnB, xvalMethod='LOO',
group=as.integer(0))
Error in xval(smallG, "ALL.AML", knnB, xvalMethod = "LOO", group =
as.integer(0)) :
no direct or inherited method for function 'xval' for this
call
I am running R Version 2.3.1, and the attached packages are Biobase
1.10.1, MLInterfaces 1.4.0, and golubEsets 1.2.4.
Following advice given for other instances of this error call I
reinstalled the Biobase package using biocLite and ran the
update.packages() function and replaced all the packages listed.
I am new to R and any help would be appreciated.
Thanks,
Mike
