Hi all, I am trying to use the filehash library to analyze a 5M by 20 matrix with both double and string data types.
After consulting a few tutorials online, it seems as though one needs to first read the data into R; then create an R object; and then assign that object a location in my computer via filehash. It seems like the benefit of this is minimizing memory allocation when running subsequent analysis (e.g., descriptive statistics, regressions, etc.) . My question is: what happens if R chokes when trying to read in the data (i.e., step 1)? Is there another library I can use to get the data read in or, alternatively, am I misunderstanding the complete functionality of the filehash library and what it can do? Apologies if this a basic question--usually I work with considerably smaller data frames and don't have much experience with memory issues and R. Thanks in advance for any advice/pointers.
