Dear List:
I have a large dataset of multiple schools. My goal is to produce a separate tex file for each school that plots some of the student achievement scores. Essentially, the aim is to develop a custom report for each school. To accomplish this, I have code for a loop that gets sourced into R and then Sweaves the multiple files to create the individual school reports.
Here is the code for the loop
schnum.list <- as.vector(unique(cmu$schid))
for(current.school in schnum.list) { school.df <- subset(cmu, cmu$schid==current.school) school.grades <- as.vector(unique(school.df$grade))
sname <- paste(paste("read", current.school, sep=""),"Rnw",sep=".") system(paste("schoolread.Rnw", paste("Reading/", sname, sep=""), sep=" ")) Sweave(file= paste("Reading/", sname, sep="")) }
However, this begins to work and then produces the following errors
Writing to file read151-496-2982.tex
Processing code chunks ...
Error in file(con, "r") : unable to open connection
In addition: Warning messages: 1: Impossible to run 'G:\SWEAVE~1\SCHOOL~2.RNW
Reading/read151-496-2982.Rnw 2: cannot open file `Reading/read151-496-2982.Rnw'
I'm not sure exactly what the impossible to run error is. I think this is on the verge of running correctly, but could use a little help.
Thanks,
Harold

It appears that you don't have the full path name for the input file correctly stated. Rather than using paste to construct names, I would suggest using file.path. You may also find it helpful to use getwd() to get the current working directory.
