C stack usage 7972740 is too close to the limit

Hi,

I got following errors when using ggVennDiagram, do you known why?

library(ggplot2)
library(ggVennDiagram)
vdat <- read.table(infile, header = F, stringsAsFactors = F)
ids <- unique(vdat$V1)
df1 <- list()
for (id in ids) {
  print(id)
  df1[[id]] <- unique(vdat[vdat$V1 == id,][,2])
}
print(str(df1))
List of 5
