QUESTION
I am pretty new to SAS, I am trying to see which songs/artists/albums have appeared most on my spotify most played csv's (2017-2020). I am getting stuck very early on trying to just set the 2017 csv as a data set. Is there anything anyone can see that I am doing wrong? Seems like this step should be pretty straight forward.

QUESTION
I have a useEffect function that must wait for four values to have their states changed via an API call in a separate useEffect. In essence the tasks must happen synchronously. The values must be pulled from the API and those stateful variables must be set and current before the second useEffect can be called. I am able to get the values to set appropriately and my component to render properly without doing these tasks synchronously, I have a ref which changes from true to false after first render (initRender), however I find the code to be hacky and inefficient due to the fact that the second useEffect still runs four times. Is there a better way to handle this?

QUESTION
I am not sure exactly how to override aesthetic properties of a custom plot made with ggplot. The only way I could think of right now was using the functionality of the grid package, though is really hackish. Maybe there is a easier way, like using guides or so from ggplot2, though I could't manage to make it work?
Below is an example where I just want to adjust the line width in the graph. Of course, I would like that to trickle down in the legend as well. So, below are my steps with grid, but any simpler solution is greatly appreciated (ideally something that doesn't need grid but just ggplot2, if possible).

QUESTION
Working on a small Rcpp package to use Boost and some of its geometry functions in C.
Finished writing the functions and everything was working well. Tested that everything was working properly (Clean and Rebuild and testing the functions) one last time before pushing up to GitHub. Once I double-checked the directory was all cleanly stored in GitHub I removed the directory from my local machine. It should also be noted that I have Roxygen2 running on this and managing the NAMESPACE file.
Upon cloning the directory back and Clean and Rebuild I get the following error:
ANSWER
Answered 2020-Apr-27 at 23:58Rookie mistake, but a serious one:
never ever keep script files in your
R/directoryeverything (and we mean everything) in the directory gets sourced (provided it looks like R code, _i.e. end in
.R)you left a script with a
library(MinimumRcpp)call in there so now your package byte-code compilation wants to source itself --> not a good planin short, keep such scripts but put them in e.g.
local/and excludelocal/via.Rbuildignore.
Plus an important style lesson
- do not leave
rm(list = ls(all = TRUE))in your code
So if you do mv R/script.R R/script.R.txt and rebuild, all is good.
(I get a half-dozen warnings because n is not a size_t but compared to one. You may want to cast it earlier.)
QUESTION
I have the following sample xml:
...ANSWER
Answered 2020-Mar-26 at 10:17Your usage of the XML document is incorrect. When you define a namespace like xmlns:h="http://www.w3.org/TR/html4/", you create a prefix that has to be used explicitly. Otherwise, you cannot query the document using this prefix if it is not assigned to any node. You would need to assign it to at least a table tag to make any use of it.
