Hello,
Our Statistics Group is evaluating the use of R for the elaboration of
some index.
We have some datasets sas and we would like to evaluate performance in
the elaborations of mean, percentile, Gini index of a population and of
a survey sample.
I need to open "a dataset". Currently I've understood that
I've to
follow a code sequence like this:
alfa <- {a moltiplicator}
memory.limit(alfa*round(memory.limit()/1048576.0, 2))
library(foreign)
hereis <- read.xport("C:/R/ { my exported file sas }")
The dimension of { my exported file sas } is 120 mega
Is correct to allocate all the file in memory in a variable ( hereis ) ?
With an alfa ( the moltiplicator ) of 2 , I have the following error:
Error: cannot allocate vector of size 214 Kb
In addition: Warning message:
Reached total allocation of 446Mb: see help(memory.size)
Thank you for any advice.
