Dear list members,
I am trying, within a lapply command, to print the name of the objects
in list or data frame. This is so that I can use odfWeave to print out a
report with a section for each object, including the object names.
I tried e.g.
a=b=c=1:5
lis=data.frame(a,b,c)
lapply(
lis, function (z) {
obj.nam <- deparse(substitute(z))
cat("some other text",obj.nam,"and so on","\n")
}
)
But instead of getting "a" "b" etc. I get X[[1L]] etc.
Any ideas?
Use a for() loop on the names: lapply is overkill here. But you could use
lapply(names(lis), function (z) {
cat("some other text", z, "and so on","\n")
## references to lis[[z]]
})
