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.

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

Install R-Package from Github
(3 answers)
Closed 2 years ago.
I'm using a package from github and functions in it are not... connected.
The main file has a function but to make that function work i need to run 4 diffrent files (3 files got a lot of functions in them and 1 has class).
Do we have any option to import whole scripts (with all the functions, classes, variables) on top of my main file so they will appear in my enviroment?
for exmaple in file "foo.R" i have a function "food = function(...)" so i do smth like
from foo.R import food
result <- 2*food(a,b,c)
or
from foo.R import *
result <- 2*foo.food(a,b,c)
like in python?
I think you should take a look at the combination of here + source. Basically, what you can do is the following:
library(here)
source(here::here('R', 'file_that_contains_a_lot_of_functions.R'))
In that way, you will get all the functions from file_that_contains_a_lot_of_functions.R in the GlobalEnviroment make it easy to work with them.
PS1: the 'R' above is because I am assuming you downloaded a mirror of the library from Github, and you are taking the functions from the R folder.
PS2: it also assumed that you generated a project at the level of the main folder of the package. What I also do is to generate an extra folder my_folder where I store everything that I create to do not disturb the workflow of the original package.
use the command source() and put in the file to run - then you will have access to all objects within.
source("path/to/your/file.R")

Better explanation of when to use Imports/Depends
(4 answers)
Closed 4 years ago.
I am developing an R package that uses third party functions
available in the Bioconductor package "methyilumi"
In the code for my R package at the very beginning I import methylumi
with library(methylumi).
During the development (I use roxygen2 and devtools) everything works fine.
However, when I install the package and run my functions, I get the error:
could not find function "methylumIDAT".
Of course everything is solved if I import the package manually, but how can I make
so that methylumi is available whenever I load my own package?
Since you are using devtools, you can add
devtools::use_package("methyilumi")
in the console, and call methyilumi::methylumIDAT in the body of your function. That way, the package is automatically listed in Imports in the DESCRIPTION file.
This sections gives the instructions for several different cases:
http://r-pkgs.had.co.nz/namespace.html#imports
This is done with the NAMESPACE file and also noted in the DESCRIPTION file. There are a few ways to import a function in NAMESPACE, but the simplest is just importFrom("[PACKAGE_NAME]",[FUNCTION_NAME). Then, in DESCRIPTION, add the package name to imports.
See this very good tutorial from Friedrich Leisch.

load data set automatically
I've built an R package and am now testing it. It requires several packages like scatterplot3d, gdata, etc.
How can I get those packages to load automatically, when someone loads my package?
Thanks!
Edit Re Comments: I've already set imports in the Description and I've set the namespaces file. I know this works because the examples I put in work when I do R CMD Check. However, if I just load up R, type library(mypackage) it gives me an error.
Edit: Solved, I moved the packages I had in the imports section to the depends section. Thank you!
