Iam using 3.2.0 version of R on 64-bit system with Windows 7 OS. I am facing a problem while using the package GEOquery for bioinformatics

library(Biobase)
library(GEOquery)
library(limma)
library(RCurl)
library(XML)
getGEO("GSE1739", GSEMatrix = TRUE)  # to get the data

​I got the error, proxy settings are OK.

ftp://ftp.ncbi.nlm.nih.gov/geo/series/GSE1nnn/GSE1739/matrix/
Error in function (type, msg, asError = TRUE) :
Failed to connect to ftp.ncbi.nlm.nih.gov port 21: Timed out

Any help in this direction will be greatly appreciated. 

​

The general recommendation in that situation is to try again later. Sometimes you just can't download right now.

> z <- getGEO("GSE1739")

And unfortunately all they have for this experiment are the MAS5.0 data, so you are stuck with that...
