i got an error while i am running a big data. Error has explained by the following sample sample

Load data 

   mdata <- as.matrix(read.table('https://gubox.box.com/shared/static/qh4spcxe2ba5ymzjs0ynh8n8s08af7m0.txt', header = TRUE, check.names = FALSE, sep = '\t'))

Install and load library 

source("https://bioconductor.org/biocLite.R") 
biocLite("impute") 
library(impute)

Sets a limit on the number of nested expressions 

options(expressions = 500000)

Apply k-nearest neighbors for missing value imputation 

res <-impute.knn(mdata)

and I got:

Error: protect(): protection stack overflow

If anybody has solution or suggestion, please share. Thanks

    Have you tried to start R like this: `R --max-ppsize 500000`? (https://stackoverflow.com/questions/32826906/how-to-solve-protection-stack-overflow-issue-in-r-studio?rq=1) – stats-hb Mar 15 '16 at 11:31

  • Got the same issue, here. Using rtsne after caret, data.table, etc. Did you solve your issue in the end? – YCR Oct 17 '17 at 15:27
