Evaluating R. I need to open "a dataset".
...x.
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 moltip...

listing nodes in paths

My interest is the numberof path between (8) and (1). Using a
standard matrix moltiplication I can see I have one pathe of length 2
and two paths of length 4.
(paths of length 2)
