...age. Python users often ask if a solution is ?pythonic?. But I am not aware of R users having any special name like ?R-thritic? and that may be a good thing.

...f the list, always combining the current set of elements into a vector, and then reduce the resulting list into a vector by combining the elements in order. This yields a named vector which we can un-name given this was not desired.n All the best, Lennart Am 28.09.24 um 07:52 schrieb Lennart Kasserra: > Hi Rolf, > > this topic is probably already saturated, but here is a tidyverse > solution: > > ``` > > library(purrr) > > x <- list( > ? `1` = c(7, 13, 1, 4, 10), > ? `2` = c(2, 5,? 14, 8, 11), > ? `3` = c(6, 9, 15, 12, 3) > ) > > x |> >...

...row where both of them are missing. Another way of writing this would be ``` data |> ? filter(!if_all(ends_with(c(".a", ".b")), is.na)) ``` i.e. don't keep rows where all columns ending in .a or .b are `NA`, which returns the same result.

Be that as it were ??, let me assure everyone that such was not my intention. The usage

Hi Rolf, this topic is probably already saturated, but here is a tidyverse solution: ``` library(purrr) x <- list( ? `1` = c(7, 13, 1, 4, 10), ? `2` = c(2, 5,? 14, 8, 11), ? `3` = c(6, 9, 15, 12, 3) ) x |> ? pmap(~ c(..1, ..2, ..3)) |> ? reduce(c) #> [1]? 7? 2? 6 13? 5? 9? 1 14 15? 4? 8 12 10 11? 3 ``` Here, we map over the elements of the list in parallel (hence pmap),

Hello, I am drawing contour lines for a function of 2 variables at one level of the value of the function and want to include a small arrow in any direction of increase of the function. Is there some way to do that? Below is an example that creates the contour lines. How do I add one small arrow on each line in the direction of increase of the function (at some central point of the contour

Base R has generic functions called any() and all() that I am having trouble using. It works fine when I play with it in a base R context as in: > all(any(TRUE, TRUE), any(TRUE, FALSE)) [1] TRUE > all(any(TRUE, TRUE), any(FALSE, FALSE)) [1] FALSE But in a tidyverse/dplyr environment, it returns wrong answers. Consider this example. I have data I have joined together with pairs of
