Hello everyone,

I'm trying to run some very basic code which worked just a couple of days ago. Now when I run it I get an error message instead.

library("TCGAbiolinks")
library("limma")
library("edgeR")
library("glmnet")
library("factoextra")
library("FactoMineR")
library("caret")
library("SummarizedExperiment")
library("gplots")
library("survival")
library("survminer")
library("RColorBrewer")
library("clusterProfiler")
library("genefilter")

GDCprojects <- getGDCprojects()

Error in if (is.character(txt) && length(txt) == 1 && nchar(txt, type = "bytes") <  : 
  missing value where TRUE/FALSE needed

What is causing this error?

Thank you very much.

GDC servers were down for maintenance.
