How do you end a pipe with an assignment operator?

I want to end a pipe with an assignment operator in R.

my goal (in pseudo R):

data %>% analysis functions %>% analyzedData

where data and analyzedData are both a data.frame.

I've tried a few variants of this, each giving a unique error message. some iterations I've tried:

data %>% analysis functions %>% -> analyzedData
data %>% analysis functions %>% .-> analyzedData
data %>% analysis functions %>% <-. analyzedData
data %>% analysis functions %>% <- analyzedData

Error messages:

Error in function_list[[k]](value) : 
  could not find function "analyzedData"
Error: object 'analyzedData' not found
Error: unexpected assignment in: ..

Update: the way I figured out to do this is:

data %>% do analysis %>% {.} -> analyzedData

This way, to troubleshoot / debug a long pipe, you can drop these two line into your pipe to minimize code rerun and to isolate the problem.

data %>% pipeline functions %>% 
   {.}-> tempWayPoint
   tmpWayPoint %>% 
more pipeline functions %>% {.} -> endPipe

Solution

It's probably easiest to do the assignment as the first thing (like scoa mentions) but if you really want to put it at the end you could use assign

mtcars %>% 
  group_by(cyl) %>% 
  summarize(m = mean(hp)) %>% 
  assign("bar", .)

which will store the output into "bar"

Alternatively you could just use the -> operator. You mention it in your question but it looks like you use something like

mtcars %>% -> yourvariable

instead of

mtcars -> yourvariable

You don't want to have %>% in front of the ->
