Hi, I am trying to use the virtualArray package, using the example code in the Vignette document, pasted below: > library(GEOquery) > library("hgu133plus2.db") > library("hgug4112a.db") > library(virtualArray) > > GSE23402 <-getGEO("GSE23402",GSEMatrix=T,AnnotGPL=FALSE) > GSE26428 <-getGEO("GSE26428",GSEMatrix=T,AnnotGPL=FALSE) > GSE23402 <- GSE23402[[1]][,1:24] > GSE26428 <- GSE26428[[1]] > exprs(GSE23402) <- log2(exprs(GSE23402)) > exprs(GSE26428) <- (exprs(GSE26428)/20*16) > > annotation(GSE23402) <- "hgu133plus2" > annotation(GSE26428) <- "hgug4112a" > > my_virtualArrays <- NULL > my_virtualArrays$iPSC_hESC_noBatchEffect <-virtualArrayExpressionSets() This code worked until about a week ago, but recently it gives me warnings and errors. In particular, I get the following warning: > Warning message: > In download.file(myurl, destfile, mode = mode, quiet = >TRUE, method = >getOption("download.file.method.GEOquery")): downloaded >length 64514067 != reported length 200 And also this error: > Now preprocessing raw data of GSE2527: Annotating expression values with SYMBOL... > Error: 2 errors; first error: > Error in array(x, c(length(x), 1L), if (!is.null(names(x))) list(names(x), : 'data' must be of a > vector type, was 'NULL' I am wondering if this issue is related to an error to the GEOquery package or the virtualArray package. Is there something wrong with my installation of R or any of my packages?
