I have a few hundred of data sets which are within one data file, I need to first of all take the subsets of each data set, and I've written commands to generate a graph and csv file. Then I want to generate the same type of graphs and csv files for the rest of the data sets. I wonder if there's a command in R which I could use?
To be more specific, I have written out the commands for a particular subset as the following, and then I need to do the same thing for the rest of the data subsets, the only thing I need to change is to modify the subset names, for example, change "seven" into "eight", "seventout" into "eightout", etc. Is there a command in R that would do this for me? (So I don't need to repeat myself modifying the names, copying and pasting the same things into R.) Thank you very much! alldata <- read.csv(file="file.csv",header=T,sep=",") seven<- subset(alldata, aserno==7, select=c(I,C,D)) ## aserno==7, so I need to change 7 into different numbers included in the data file## sevenout <- subset(seven, I=="a" & D>0, select=c(I,C,D)) f <- function(sevenoutf) nrow(sevenoutf) sevennumber <- ddply(sevenout,.(C), f) colnames(sevennumber)[2] <- "N" sevenout$N <- sevennumber$N [match(sevenout$C, sevennumber$C)] sevenout=data.frame(sevenout,"time"=c(1:nrow(sevenout))) plot(sevenout$time, sevenout$N, type="n") lines(sevenout$time,sevenout$N) # the result that I need write.csv(sevenout, "sevenM.csv", row.names=FALSE) # the result that I need -- View this message in context: http://r.789695.n4.nabble.com/How-to-generate-same-type-of-graphs-using-the-previously-written-commands-for-a-few-hundred-similar--tp3661026p3661026.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
