Hi everyone, I am new to R and interested to learn Social Network using R. Currently I am stuck on reading mtx file.
I have spend a lot time to search via Google about reading mtx file and could not find the answer.
The problem:
-
Downloaded soc-karate.mtx file from karate | Social Networks | Network Data Repository
-
Then tried the following as per https://stat.ethz.ch/R-manual/R-devel/library/Matrix/html/externalFormats.html:
str(pores<-readMM(system.file("soc-karate.mtx",package="Matrix")))
-
It just shows:
1:
Thank you!
"> str(pores<-readMM(system.file("soc-karate.mtx",package="Matrix")))
1: "
If you are interested in this specific data set, rather than the mtx matrixmarket format generally, several R network packages have it built in, such as igraph and
library(hydra)
data("karate")
