Here is an example of how to create the init files:
x <- read.table(textConnection(" PA1 PA2 PA3 PB1
j=1 12 2 1 5
j=2 10 3 2 4
j=3 11 4 3 6"), header=TRUE)
closeAllConnections()
for (i in 1:nrow(x)){
outfile <- file(paste("init.", i, ".txt", sep=''), "w")
for (j in colnames(x)){
writeLines(paste(j, '=', x[i,j], sep=''), outfile)
}
close(outfile)
}
This will create a file that will look like this:
> readLines('init.1.txt')
[1] "PA1=12" "PA2=2" "PA3=1" "PB1=5"
