Hi,

I'm using getGEO to obtain the serie GSE18154 and I encounter the following
error:

> gse18154 <- getGEO("GSE18154")
Found 1 file(s)
GSE18154_series_matrix.txt.gz
trying URL '
ftp://ftp.ncbi.nih.gov/pub/geo/DATA/SeriesMatrix/GSE18154/GSE18154_series_matrix.txt.gz
'
ftp data connection made, file length 1891349 bytes
opened URL
downloaded 1.8 Mb

Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
  scan() expected 'a real', got '"GSM453789"'
In addition: Warning messages:
1: In grepl("^!Series_", dat) : input string 38 is invalid in this locale
2: In grepl("^!Series_", dat) : input string 46 is invalid in this locale
3: In grepl("^!Sample_", dat) : input string 38 is invalid in this locale
4: In grepl("^!Sample_", dat) : input string 46 is invalid in this locale

I think part of the problem may be the extra quotation marks (when comparing
to another matrix file that works), after downloading it and manually
removing the quotation marks, getGEO load the local file with less warnings:

> gse18154 <- getGEO(filename="GSE17308_series_matrix.txt")
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
  scan() expected 'a real', got 'GSM433039'
