This is the first time I'm working with Big Matrix and bigmemory and biganalytics.
I created a big matrix with the following code:
BDdata<-read.big.matrix(file.BDdata,sep = ",",header = TRUE)
I finished working, saved my Work Environment and closed R Studio. When I loaded my file and environment to continue working, the big matrix objects show: "Object with Null pointer"
So I'm wondering if each if time I close and open I will have to run all the code on Big Matrix.
Also, I've tried applying conventional code to the Big.Matrix but it turns the object into a regular matrix and when I want to convert it back to Big.Matrix, the program crashes.
If you have any references on how to work with Big Matrix, I'll appreciate it much. From how to do summaries, delete variables, to modeling (PCA, clustering,etc).
Thank you!
