using save() to work with objects that exceed memory capacity
...e in save().
My specific question to the list: How do I capture the string that names
an object I want to save, in such a way that I can use it in a function
that calls save()?
For example, suppose I create a matrix and then save it follows:
> mat<-matrix(1:9,3,3)
> save(mat, file="matfile")
Then I get a file of the kind I'd like: the command 'load("matfile")'
retrieves the correct matrix, with the original name 'mat'.
Further, if I instead save it this way:
> objectname<-"mat"
> save(list=ls(pattern=objectname), file="matfi...

readMat - how to retrieve the variables
...te_flow (date)
a.river1.precip (precipitation values)
a.river1.date_precip
a.river2.flow
a.river2.date_flow
a.river2.precip
a.river2.date_precip
I have used readMat to load the variable a in R, however I have no idea how
readMat translates a. I managed to get some values out of
data=readMat("matfile.mat")
data$a[,,1]$river1[,,1]$flow -> Why do I need [,,1]? Why not
data$a$river1$flow?
Many thanks

[Reading mat files into R]
...t resolve my problem.
When I want to load mat file, created by Matlab 2011b release by using
following commands:
*require(R.matlab)*
*require(utils)*
*require(Rcompression)*
* *
*dataPath<- Q:/data/mat”;*
*matList<-list.files(path = dataPath) *
*matQuantity<-length(matList)*
*MatFile<-readMat(file.path(paste(c(dataPath,’/’,matList[1]),collapse=””)),
sparseMatrixClass=”matrix”);*
* *
my CPU usage is increasing even till 100% but memory usage stays very low.
File is not finally loaded.
This whole operation do not return any error, warning, etc. You can wait
forever (even i...
