export default WithTransition;

Error: could not find function ... in R
(10 answers)
Closed 10 days ago.
I'm having real trouble running the function write.xlsx - the error "could not find function "write.xlsx"
I've already tried to:
Install the packages xlsx, readxl, writexl, XLConnect but no one of these is working.
Install Java JRE, but it's not working as well
Have you guys ever had a similar problem before?
I'm really needing to start running those flows which are properly working in other machines.
PS: I'm a beginner in the R coding
After installing the package xlsx you should also load the library in order to use the function, like this:
library(xlsx)
If you're just going to use the function one time you can call it without loading the library first like this:
xlsx::write.xlsx(data, file = "file.xlsx")
Hope this helps

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)")

Load R package from character string
(2 answers)
Closed 6 years ago.
I would like to install/load packages from a different location that is default. I dont have admin privileges so I cant access my .rprofile from the control panel.
My thought was I could just make a different library function, so I dont have to type a lib.loc statement every time i want to install/load a function. This is what i think the "liBerty" function should look like.
liBerty <- function(a) {
require(a,lib.loc="C:\\Users\\bert\\Documents\\rpackages" )
}
liBerty(tm)
The error I am getting states "there is no package 'a'.". Is there a way i can write this function to accomplish my task?
The function needs to also be modified for installing packages
install.Bertages<-function(b){
install.packages(b,lib="C:\\Users\\bert\\Documents\\rpackages")
}
liBerty<-function(a){
require(a,lib.loc="C:\\Users\\bert\\Documents\\rpackages",
character.only=TRUE )
}
install.Bertages("lubridate")
liBerty("lubridate")

How to use `moment.js` with Meteor?
(5 answers)
Closed 6 years ago.
I'm sorry if this question is stupid, Googling got me nowhere.
I want to install MomentJS atmosphere package
I add this command to my packages file:
momentjs:moment
How do I use it? I've used every variation of this I can think of:
import {moment} from 'momentjs';
I've tried momentjs/moment, moment/momentjs, ... how do I use moment?
You have import like this :
import {moment} from 'momentjs:moment';
Basically you have to add full package name while importing.
