Yes but this exageration precisely misses the point.
Concerning your examples:

best associated with a package. I think it

Dear R-devel,
The most popular piping operator sits in the package `magrittr` and is used
by a huge amount of users, and imported /reexported by more and more
packages too.
Many workflows don't even make much sense without pipes nowadays, so the
examples in the doc will use pipes, as do the READM
Dear all,
`rbind()` returns a zero row data frame when binding zero column data
frames, see example below:
``` r
# a data frame with 1 row and 0 column
x <- data.frame(row.names=1)
x
#> data frame with 0 columns and 1 row
rbind(x,x)
#> data frame with 0 columns and 0 rows
```
I would have expect
Dear all,
`?Syntax` documents that `?` has the lowest precedence, right under `=`.
Indeed it reads:
*The following unary and binary operators are defined. They are listed in
precedence groups, from highest to lowest. *
and ends the list with
*<- <<-* *assignment (right to left)*
*=* *assignme
Dear all,
There was some discussion lately on twitter (
https://twitter.com/geospacedman/status/1164208293377691648 ) about the
status of the colon equal operator. I'm sure it has been discussed in the
past but I couldn't find anything, I'll start by clarifying all i can by
myself to have strong r
Indeed it's a RStudio issue as diagnosed by Hugh, and is still an issue
with the latest version.

Dear all,
The help for `?install.packages` decribes, in the `pkg` argument
description :
> If this is missing, a listbox of available packages is presented where
possible in an interactive R session.
In fact running it with a missing argument triggers an error :
install.packages()

Dear all,
`head()` returns a problematic output when a character is fed to its `n`
parameter.
doubles and logicals are converted to integer as if `as.integer` was used,
which I think is intuitive enough :
```
head(1:10, 4.1) # [1] 1 2 3 4
head(1:10, 4.9) # [1] 1 2 3 4
head(1:10, TRUE) # 1

Hi,
`stats::chisq.test` checks that x and y each have at least 2 levels AFTER
filtering on complete cases.
It makes sense but the error message is misleading : “'x' and 'y' must have
at least 2 levels”
Here’s how to reproduce the issue :
x <- structure(c(1L, 1L, 1L, 2L, 1L, 2L), .Label = c(
13 matches
