R help - Jun 2018 - Storing tableGrobs in a list

Hi, I'm trying to generate tableGrobs in a loop, store them in a list so I
can use it in a call to gtable_combine().

L1<-list()
for (i in seq( ... )) {
   L1[i] <-tableGrob( ... )
}

gtable_combine(L1, along=1)

On the assignment inside the loop, I get "number of items to replace is not
a multiple of replacement length" which I'm guessing has to do with the
tableGrob object not "fitting" in the list but am not sure how to fix
it.

Thanks in advance for any pointers.

?`[[`

and read the discussions of indexing in the Introduction to R document that
comes with R. Also, find a way to predict the number of elements you will need
as making this a habit will pay off big time when you work with large amounts of
data:

L1<-vector( "list", N )
for (i in seq.int( N )) {
   L1[[i]] <-tableGrob( ... )
}

stripped anyway and that often leads to partial corruption of your message. Read

Thanks for the replies. Wasn't aware that Gmail on Android sent HTML by
default, apologies. 

Storing the tableGrob-s in a list worked but for some reason grid.arrange
complains on output from gtable_combine() using lists vs individual tableGrob-s.

# works when supplying individual tableGrobs

p1<-gtable_combine(p11,p22, along=2)
p2<-gtable_combine(p11,p22, along=2)
grid.arrange(p1,p2,ncol=2)

# breaks when supplying a list of tableGrobs, error from grid.arrange()

p1<-gtable_combine(L1,along=2)
p2<-gtable_combine(L2,along=2)

grid.arrange(p1,p2,ncol=2)

Error in gList(list(list(grobs = list(list(label = "status", x = 0.5,?
:
? only 'grobs' allowed in "gList"

Also tried, still no go 

p1<-do.call(gtable_combine, list(L1,along=2))
p2<-do.call(gtable_combine, list(L2,along=2))
