My laptop has 4GB RAM. I am trying to impute missing values of temperature in the training data set using the mice package. I came across this error while imputing: > Error: cannot allocate vector of size 12.2 Gb 1. How can I resolve this issue? 2. Any online computing environment where I can perform the imputation operation? Any feedback appreciated. Regards, Saurabh Jain ---

If you have RAM problems you should process each sample separately instead of processing the whole dataset at one time. ---
