I'm using R-3.4.4 and TCGAbiolinks package for the analysis of GDC data.
Till today i have reintalled R and R studio for 5 times but one error comes
when i analyze the GDC data at the step GDCprepare. the data i am using is
not a legacy data of GDC data portal.
I think the problem is with my Laptop only because i have run the same
commands in another PC and there was no error. Thus i have uninstalled and
again installed the R but the error is not going.
Today i have installed the developer version of TCGAbiolinks. and the error
is still there.
I have attached the code used and the session info.
Every time i run this GDCprepare command this same error comes as biomart
service is not available. So i had contaced the Biomart people but they
said that the Biomart is working fine.
below is the complete R code i am usign with the corresponding error,
