Received "Error in split_chain(match.call(), env = env) :
Have you tried installing the latest {magrittr} and then loading {tidyverse} after all other packages? I know very little about the cause of the error, but some quick Googling turned up this temporary solution. For a permanent solution you need to figure out which other package is at fault and get the author to fix it.

Hi folks,
I had originally thought this issue was specific to just me so I di… dn't file an issue report, but I see based on this twitter thread I am not alone.
The error appears to occur with the latest version of magrittr and an internal function `magrittr:::split_chain`. If I force install v1.5 via `devtools::install_github('tidyverse/magrittr@v1.5')` the issue is resolved.
I'm struggling to come up with a reprex for this, but if I try to use a pipe on something as simple as below in the context of an existing function within a package (where the package accesses the pipe via `%>% = magrittr::`%>%` in a utils.R file):
```r
c("a","b","c") %>% purrr::map(print)
Error in split_chain(match.call(), env = env) :
could not find function "split_chain"
```
While browsing within that function, the `%>%` is clearly referencing the old version of the pipe:
```r
function (lhs, rhs)
{
parent <- parent.frame()
env <- new.env(parent = parent)
chain_parts <- split_chain(match.call(), env = env)
pipes <- chain_parts[["pipes"]]
rhss <- chain_parts[["rhss"]]
lhs <- chain_parts[["lhs"]]
env[["_function_list"]] <- lapply(1:length(rhss), function(i) wrap_function(rhss[[i]],
pipes[[i]], parent))
env[["_fseq"]] <- `class<-`(eval(quote(function(value) freduce(value,
`_function_list`)), env, env), c("fseq", "function"))
env[["freduce"]] <- freduce
if (is_placeholder(lhs)) {
env[["_fseq"]]
}
else {
env[["_lhs"]] <- eval(lhs, parent, parent)
result <- withVisible(eval(quote(`_fseq`(`_lhs`)), env,
env))
if (is_compound_pipe(pipes[[1L]])) {
eval(call("<-", lhs, result[["value"]]), parent,
parent)
}
else {
if (result[["visible"]])
result[["value"]]
else invisible(result[["value"]])
}
}
}
<bytecode: 0x562bfab03748>
<environment: 0x562bfab045f0>
```
While outside of debug / the package itself, assigning `%>%` = magrittr::`%>%` produces the new version version of the pipe correctly.

I'm hoping someone else who's having this issue can provide a cleaner reprex.

Uninstalled R, R studio and tried with latest versions, no luck with the same Win 10 PC.
Thanks.. I came through the link you shared too.
Starting in a fresh R session, what packages are you loading (in order) when %>% results in the "split_chain" error?

Uninstalled R 3.6.3, 4.1.0 and 4.1.1, also R Studio (rstudio may not necessarily)
Reinstall 4.1.1, install the tidyverse and dependencies package itself, fixed the errors. No more "split_chain" error.
Assuming somewhere conflicts the packages during R version upgrades. (don't know exactly where .. )
