Dear R family,i am trying to plot and save, simultaneously,  about 1000. the name of each plot is contained in "names" file. when i run this loop, i get an error. 
"Error in plot.new() :   Unable to open file 'C:/R/SAVEHERE/myplot_Tak.jpg' for writing". could you please correct the mistake in the loop?
>names<-(names(sp))
>for(a in seq_along(names)){
>mypath <- file.path("C:","R","SAVEHERE",paste("myplot_", names[a], ".jpg",sep = ""))
>jpeg(file=mypath)
>for (i in seq(1)){
>b<-lapply(res,function(x) {if(is.data.frame(x[,-1])) rowMeans(x[,-1]) else mean(x[,-1])})
>lapply(seq_along(res), fun)
>fun <- function(i){
>matplot(res[[i]][,-1], type="l",col="grey")
>lines(b[[i]], lwd = 2, col = "black")
>}}
>dev.off()
>}


thanks in advance
