====== List of titles for WoS islands ======

===== Second version (September 2013) =====

WoS2Pajek 1.2 (September 2013) creates also a csv file ''titles.csv'' with works names and their title, first author, journal and year of publication. This file can be merged with a subnetwork (island) net file to produce a list of titles of works contained in the subnetwork. It uses the Python csv library.

Function in R to create a list:
<code>
#

# (name, year, title) for vertices of a subnetwork from file netFile.
# The titles for all (DC>0) vertices are stored in the table T.

  f <- function(L){
    s <- unlist(strsplit(L,"[[:space:]]+"))

    t <- substr(t,2,nchar(t)-1)
    if(substr(t,1,1)=="=") t <- substr(t,2,nchar(t))
    return(t)
  }
  getYear <- function(x){

  for(k in 1:nn){j <- which(T$name==N[k]); tit[k] <- ifelse(length(j)==0,"***",T$title[j])}
  D <- data.frame(name=as.character(N),year=year,title=as.character(tit))
  write.table(D,file=csvFile,sep=";",fileEncoding="UTF-8",qmethod="double",row.names=FALSE)
  return(D)
}

# setwd("D:/Data/Centrality/net")
# source("D:\\Data\\Centrality\\net\\res\\description.R")
# T <- read.csv("CentTitles.csv",header=TRUE,sep=";",colClasses="character")
# d <- description("mainPath.net","mainPath.csv",T)
# d <- description("islands2.net","islands2.csv",T)
</code>

Application:
<code>
setwd("D:/Data/Centrality/net")
source("D:\\Data\\Centrality\\net\\res\\description.R")
T <- read.csv("../WoS/CentTitles.csv",header=TRUE,sep=";",colClasses="character")
d <- description("./res/mainPath.net","./res/mainPath.csv",T)
</code>
Instead of the command ''T <- read.csv'' we can use also
<code>
T <- load("CentTitles.Rdata")
</code>
