7. September 2013 / 24-26. August 2013
In R make from WJ.net a CSV file with list of all journal titles. On 7. September an improved version was made with adding the code of each journal:
> setwd("E:/Data/Centrality/net")
> Code <- function(x) paste(substr(unlist(strsplit(x," ")),1,1),collapse="")
> net <- file("../WoS/WJ.net","r")
> L <- readLines(net,n=1); L <- readLines(net,n=1)
> unlist(strsplit(L,"[[:space:]]+"))
[1] "*vertices" "1044802" "996348"
> LL <- unlist(strsplit(L,"[[:space:]]+"))
> n1 <- as.integer(LL[3]); n <- as.integer(LL[2]); n2 <- n-n1
> c(n,n1,n2)
[1] 1044802 996348 48454
> S <- as.data.frame(scan(net,skip=n1,nlines=n2,what=list("","")))
Read 48454 records
> close(net)
> names(S) <- c("vtx","lab")
> cod <- character(n2)
> for(i in 1:n2) cod[i] <- Code(as.character(S$lab[i]))
> T <- data.frame(num=1:n2,par=1:n2,vtx=as.integer(as.character(S$vtx)),
+ cod=as.character(cod),lab=as.character(S$lab))
> head(T)

Use Excel to make a partition (assign the same number to equivalent
journals) and save it as journalsPart.csv. Using R create the corresponding Pajek's partition journals.clu:
> S <- read.csv2(file="journalsPart.csv")
> head(S)
num par vtx cod lab
1 1 1 995784 * ******
2 2 2 995785 PIP P IEEE PIMRC

> n1 <- 995783
> P <- c(rep(0,n1),S$par)
> clu <- file("Journals.clu","w")
> cat("% jornals partition - ",date(),"\n",file=clu)
> cat("*vertices ",n1+nrow(S),P,sep="\n",file=clu); close(clu)
Using Pajek shrink the WJ network.
