Error: could not find function "%>%"
(5 answers)
Closed 3 years ago.
I am trying to run a line of code in R using the dplyr package. dplyr is installed and the package appears to have loaded correctly, but does not recognise the %>% function.
The code I am attempting to run is -
reptiledata2 = reptiledata %>% filter (START_YEAR>=1980)
This leads to the error:
Error in reptiledata %>% filter(START_YEAR >= 1980) : could not find function "%>%"
This code has previously worked for me before, but for some reason is not working today. Have also tried to load magrittr package but this does not solve the issue either.
Install or reinstall dplyr package.
install.packages("dplyr")
If does not work, try to remove it and reinstall.

I recently updated Amelia to the most recent version 1.8.0, built: 2021-05-26.
Now, when I try to use the amelia() function, I get the error
Error in emarch(x.stacked$x, p2s = p2s, thetaold = NULL, tolerance = tolerance, :
function 'Rcpp_precious_remove' not provided by package 'Rcpp'
I updated Rcpp, but it was not solved.
Any help please?
It seems that I first had to uninstall and reinstall (rather than update) the Rcpp package.
Problem solved now!

I want to use spread function from tidyr package but my RStudio says
"Error in spread(., nama_event, created_at) :
could not find function spread"
Therefore, I want to install tidyr package but it doesn't exist in RStudio 1.4.1.
Instead of using spread you should use pivot_longer.

To install a package, you shoud use install.packages.

I am using Google Colab to work on a final project with a set of groupmates. Unfortunately, Colab is not working and I am getting this error. I was able to successfully install and then call the library for the package but when I run the DDPLY code Colab doesn't work.
If anyone can provide insight as to how to fix this it would be greatly appreciated!
It looks like you are loading dplyr and not plyr.
Calling it with either library(plyr); ddply() or plyr::ddply() should solve your issue
I think ddply is not in dplyr (daft I know!) it is in plyr
So you need
library (plyr)
(And on first use a install.packages("plyr") too)

What's wrong with my code?
Here is my code:
paths_allowed("https://collections.ed.ac.uk/art)")
Here is the error message:
Error in paths_allowed("https://collections.ed.ac.uk/art)") :
could not find function "paths_allowed"
paths_allowed is a function of the package robotstxt.
To use the function, you need to install the package first.
Then, after loading the package with library, you will be able to use your function.
install.packages("robotstxt")
library(robotstxt)
paths_allowed("https://collections.ed.ac.uk/art)")
If you don't want to load the package you can alternatively call the function with :: operator in this way:
robotstxt::paths_allowed("https://collections.ed.ac.uk/art)")

dplyr::select function clashes with MASS::select
(6 answers)
Closed 1 year ago.
I am encountering a strange problem in using packages MASS and dplyr together in R using RStudio. The following code
library(dplyr)
select(iris, starts_with("Petal"))
works and gives me the right output. But if I try to load MASS package and use the same code
library(MASS)
library(dplyr)
select(iris, starts_with("Petal"))
I get an error
select(iris, starts_with("Petal"))
Error in select(iris, starts_with("Petal")) :
unused argument (starts_with("Petal"))
Is there a known issue with using dplyr with MASS in RStudio. I am loading dplyr after MASS so as not to mask the select from dplyr. I have un-installed and re-installed my RStudio also, but the error persists.
I am using R Version 3.2.2, MASS version - 7.3-45 and dplyr version 0.5.0
Any help would be highly appreciated!

Both packages have a select function.
Use dplyr::select() or MASS::select() as needed to prevent errors.
Another popular conflict is the dplyr::filter vs signal::filter.
If you don't want to type the package name every time you can type once dselect <- dplyr::select and then use dselect all the time instead.
