Chris -
You can solve your problem by removing the print
statements and replacing them with
answer = list(org.plot[org.plot$sub %in% ex.plot,],
new.pl[new.pl$yar %in% "1991",],
new.pl[new.pl$yar %in% "1993",])
prefix = sub('-','.',ex.plot)
names(answer) = paste(prefix,c('.new','new1991','new1993'),sep='')
return(answer)
That will return a list with three dataframes having the names that
you specified.
If you actually want to create separate objects in your workspace, you
could look at the help page for the assign function.

Hi,
I'm trying to create a function to return three dataframes for later use in
a graphic so I want the return from the function to give me dataframes and
with unique names relating to the variable they are based on.
For example.....
sub<-c("6-1a","6-1a","6-1a","9-2b","9-2b","9-2b","7c","7c","7c")
yar<-rep(1991:1993,3)
x1n<-c(4,6,3,6,4,7,9,4,2)
y1m<-c(3,7,5,8,4,3,6,7,8)
prac<-data.frame(sub,yar,x1n,y1m)
plot.restrut<-function(org.plot,ex.plot) {
new.pl<-org.plot[org.plot$sub %in% ex.plot,]
new.pl.st<-new.pl[new.pl$yar %in% "1991",]
new.pl.fin<-new.pl[new.pl$yar %in% "1993",]
print(new.pl)
print(new.pl.st)
print(new.pl.fin)
}
plot.restrut(prac,"9-2b")
######
I would like the output to be one dataframe with the name "9.2b.new" which
is new.pl in the example
Another data frame to be "9.2bnew1991" and another dataframe "9.2bnew1993"
I want the dataframe names to relate to the variables they have come from
because I want to use the same function to extract lots of subsets of my
data.
Thanks
Chris
