Thanks for all the input.
It seems like there is no way around introducing names for the list items,
but the namedList-function is really neat.
Function returns are not at issue for me, I rather want to use it on plots
or outputs in the console.

You can automate the adding of the names to the list with the following
function, so you
can replace the
dflist<-list(df1,df2,df3)
names(dflist)<-c("df1","df2","df3")
with
dflist <- namedList(df1, df2, df3)
If you supply names, such in
dflist <- namedList(df1, Second=df2, log(df3))
it will

You do realize that the `for` function returns NULL, I hope? I was surprised

thanks, that would work, but isn't there a maybe more elegant way to
"extract" the name from the df variable within the current for (df in
list()) loop?

Hi Kai,
One way is to name the components of your list with the names of the
data frames:
df1<-data.frame(a=1:3)
df2<-data.frame(a=4:6)
df3<-data.frame(a=7:9)
dflist<-list(df1,df2,df3)
names(dflist)<-c("df1","df2","df3")
for(i in 1:length(dflist)) cat(names(dflist)[i],"\n")
df1
df2
df3

Hi everybody,
I just can't figure this out:
I have a loop trough several dataframes such as
for (df in list(df1, df2, df3, ...)) {
..some functions with df..
}
now I want to print out the current dataframes name (ie the list items
name) with the cat command before the actual functions to have
8 matches
