The table you are looking for indeed does not any longer exists. Kai.
Anything created within a function generally disappears as soon as it exits as
the only pointer to it goes away and garbage collection can eventuially reuse
the space.
The code you wrote should end with:
MyNamedVariable <- f1(iris, Species)
It will then have a pointer to it and will show up as that name in the RSTUDIO
window for Environment when it is the selected function of the upper right.
By just writing this:
f1(iris, Species)
What you effectively did at the console level is this becue of automatic
printing:
print(f1(iris, Species))
As soon as the printing is done, nothing is pointing at the memory location in
the current environment or any environment.
There are, of course, ways for your f1() function to create a variable and save
it in another environment such as global or parent under a designated name, but
the easiest thing to do is to save teh result as shown as the return value of
the function. Again, note, that if the place the function is called from is
another function, any variables within it will disappear again when it exists,
...
Not suggesting you use it, but there is an assignment operator that assigns
outside the immediate function using <<-
But back to your code, tell us more about the function view() you call several
times in f1() and I assume you used it in debugging and it is not to be kept.
On my machine the normal function is capitalized as View() so I am guessing you
are getting the tidyverse version with view() in all lower case. It does return
the object viewed and as that is the last line, it will return the object from
the function. But probably not the best or most obvious way to return something
as using the more standard View() function returns NULL.

Subject: [R] how to find the table in R studio
Hi all,
I created a function in R. It will be generate a table "temp". I can view it in
R studio, but I cannot find it on the top right window in R studio. Can someone
tell me how to find it in there? Same thing for f_table.
Thank you,
Kai
library(tidyverse)
f1 <- function(indata , subgrp1){
subgrp1 <- enquo(subgrp1)
indata0 <- indata
temp <- indata0 %>% select(!!subgrp1) %>% arrange(!!subgrp1) %>%
group_by(!!subgrp1) %>%
mutate(numbering =row_number(), max=max(numbering))
view(temp)
f_table <- table(temp$Species)
view(f_table)
}
f1(iris, Species)
