Off topic:Problem with getGEO

Question

[sina.majidian]

Dear all

I want to extract the expression values of a gene from GSE75970 in my Mac Sierra 10.12.6 with R 3.3.1 and RStudio Version 0.99.903. First I run this code:

library(GEOquery)
gse <- getGEO("GSE75970")

I faced this:

Furthermore, I used

    options('download.file.method.GEOquery' = 'curl')

But did not work.

Please help me.
