Building a vignette - r

I was developing a package when I found a new error when building the package.The error makes reference to a line that previously didn't have any problem and I didn't modify. However it run smoothly in a fresh R session when I ran the code or knit the vignette alone.
Long story short: I found that this error happens when a suggested package (by my package's DESCRIPTION) is loaded before my package.
How can I control this?
The reason of the error is that my package (A) has a function is named exactly the same as the other package (B) because it does the same kind of process, but I use a different name for the same arguments (and in my version I provide other arguments as well). A solution I found is to use A::function, but that would be uglier to the reader. Is there any other solution?
This didn't happened in previous cycles of development. I have observed it on the latest R version R version 3.4.3 (2017-11-30) -- "Kite-Eating Tree" and in the devel version of R. The packages are build using both R CMD build package and devtools::check()
The conflicting package is in Suggests: part of the DESCRIPTION file of the package
This question might be related to this other one.

R studio install package failed

I tried to install the packages in the following way:
pacman::p_load(tidyverse, lubridate, zoo,
timetk, modeltime,
trelliscopejs, seasonal,
tsibble, feasts, fable)
However, I got the below errors:
I'm not sure what's wrong, I'm using the latest R version 4.2.1, the warning seems to suggest that need to change to 4.1.3, is there anyway to install those packages without changing the version?
The problem is not related to the package in itself. The warning about the version only tells you that the last time this package was built was on R 4.1.3, but it should work on R 4.2.
The problem is that the place where R searches this package doesn't exist. If you go here: https://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/, you will see that the last version of R is 3.4, whereas you're looking for a package built in R 4.1 (see the version in the URL address in the error message).
Here's some advice to solve this (I can't reproduce your problem so I can't be sure this works): if you're using RStudio, go to "Tools -> Global Options -> Packages". I think that under "Primary CRAN repository", there should be the name of the current place where R searches for the files to install each package. You can change this: either pick "Global (CDN) - RStudio" or any other that is not too far from your location. Then restart R and try reinstalling the packages.

Difficulty installing a package in R linux, dalton_rqi

Downloaded package from below URL.
Attempted to install using below command; response shown.
library(dalton.rqi,lib.loc='/home/X/Desktop/')
Error: package ‘dalton.rqi’ was built before R 3.0.0: please re-install it
https://my.clevelandclinic.org/departments/anesthesiology/depts/outcomes-research/risk-quantification
It appears this is a compiled package that maybe I don't have the source for? Is there a way to force install of the package? I'm unable to install using Rstudio GUI in its current form as a zip. Tried repackaging to tar.gz has Rstudio was looking for and also had a non-zero exit status error.
Any ideas?
I'm afraid this can't be achieved directly. The error message says it well: to use a package in R it needs to be built on an R version matching yours.
I can suggest two ways to move forward:
Contact the authors, ask for the R sources (it is somewhat surprising they did not make them available in the first place), and build the package yourself.
Downgrade your R version as far back as needed to match the one this pre-built package used.

R Studio 1.1.456 (Windows): Why do I sometimes have to install binary packages instead of installing from the source?

I am asking this question because I recently solved a problem installing R Shiny (see below). However, the answers I find don't expand in detail about why this problem occurs and I really want to understand to improve my knowledge of R and why these things happen.
So my attempt to install Shiny in RStudio failed and I believe these are the important error messages:
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
namespace 'httpuv' 1.3.3 is being loaded, but >= 1.4.3 is required
ERROR: lazy loading failed for package 'shiny'
* removing 'C:/Program Files/R/R-3.2.2/library/shiny'
* restoring previous 'C:/Program Files/R/R-3.2.2/library/shiny'
Warning in install.packages :
running command '"C:/PROGRA~1/R/R-32~1.2/bin/x64/R" CMD INSTALL -l "C:\Program Files\R\R-3.2.2\library" C:\Users\Sam\AppData\Local\Temp\RtmpuI3XHe/downloaded_packages/shiny_1.1.0.tar.gz' had status 1
Warning in install.packages :
installation of package ‘shiny’ had non-zero exit status
I went through the usual processes first to find a solution.
Checked my RStudio was up to date
Checked for and installed package updates
Among the further solutions I tried were:
Downloading the package directly from the R Studio interface
Using devtools to install Shiny from Github
Using install.packages("shiny", dependencies=TRUE).
None of these solutions worked and I believe it is to do with the dependency httpuv, but I'm not sure why.
So in the end the code I was able to use is: install.packages('shiny', type = "binary") and this allowed me to begin using Shiny.
While it wasn't too difficult for me to find a work around for this problem, I would really appreciate someone taking some time out of their day to explain why my version of RStudio in Windows (Version 1.1.456) doesn't support the source package of Shiny and why installing the binary package works. I hate fixing an issue but having zero understanding of it.
R version 3.2.2
Thank you.
Binary versus Source Code Options and Issue
You are experiencing the push-pull friction between the old and new code and R environment dependencies. The reality here is you have to choose between stability and progress. It is difficult to have both.
Consider:
You are running R version 3.2.2 in binary form, that R version was released on August 15th 2015. Yet, you are trying to install the latest source code version of Shiny.
There is a 3-year delta between the package source code version and R version you are using. The package code and R environment source code have evolved.
A lot of changes have occurred between then and now in the compile and source code environment.
Think of it this way.
The binary package image is a snapshot of the compile and source code environment assumptions at the time of compilation. If you download the current source code image you are using a snapshot of the current code environment (Now) which includes literally thousands of small incremental changes to the assumptions and dependencies in the source code files and compile environment. if you look in the shiny package description you note:
Shiny depends on httpuv which depends on Rcpp
httpuv is built on top of the libuv and http-parser C libraries.
To get httpuv to compile from source you'll need to match the R Environment, the dependent libraries and source dependencies manually. No small feat.
Case in point to compile the above packages from source code (github) you'll likely be using Devtools which if you download in binary form was compiled under R version 3.2.5.
The changes, assumptions and inter-dependencies make for a complex backport compile situation. Hence, the advantage of binary package snapshots.
Options:
In this situation, you generally have two options. You can either:
Download a source version that is old that matches your R version and environment.
The downside of this approach is you cannot access current package features.
The upside is that the package and R environment match historical context.
Upgrade to a current R environment
The downside of this approach is you have to roll with the R releases.
The upside is that you get to gain access to the latest package features made available in the current source code.
Solution Options:
How to do the above? In the first case, you might use devtools::install_git and pull the source for a particular branch or version of a package and compile it. In the second, you can upgrade your environment, and then pull and upgrade your packages.
If you want to work off a particular R environment version you have to use the binary versions. Why? These will match the R environment version coding environment assumptions.
This is a classic problem highlighting the push-pull between current code and old code. You have to choose between stability and progress. It is difficult to have both.
I hope the above helps explain the situation.

Package dependency issue when testing for submissin to CRAN

I am developing an R package for which I wrote some test files using R package testthatand placed the files under tests folder. I ran R CMD build on a Linux machine with R version 3.0.0. The command failed because testthat package requires R version at least 3.1.0.
Two following things I can do, but I am not sure which is better.
I can remove whole things in tests folder, so that my R package will also work for R version less than 3.1.0. As I notice, test files are not required for building an R package. Those are only useful for the developer.
I can keep all test files, but explicitly mention Depends: R (>= 3.1.0) in the DESCRIPTION file. The downside is that: (1) the package will be available to less users; and (2) more important, it depends on testthat package. Whatever updates there might affect my package potentially.
Which one do you think is better?
[update]
I followed the suggestion from # hrbrmstr, which is, I first built the package using R 3.1.0, and then check it on a Linux machine with R 3.0.0. But I still failed. The log is as follows.
* checking package namespace information ... OK
* checking package dependencies ... ERROR
Package suggested but not available: ‘testthat’
The suggested packages are required for a complete check.
Checking can be attempted without them by setting the environment
variable _R_CHECK_FORCE_SUGGESTS_ to a false value.
Any ideas to fix this issue?Or should I take approach 1 or 2 as stated above?

R 3.0.1 package build warning

I'm building R packages in R 3.0.1 on a Windows machine, using Rtools30 and the 'Build' tools associated with RStudio, which I assume is tied in with devtools (which is up-to-date). My typical process to build a package is:
Load All
Reoxygenize
Build & Reload
Check
Build Source Package
If everything goes without errors or warnings, I then:
install.packages("foo.tar.gz", repos=NULL, type="source")
Since upgrading to R 3.0.1, I now get this warning:
Warning in install.packages :
foo.tar.gz is not available (for R version 3.0.1)
I also tried before installing, and it did not get rid of the warning:
options(install.packages.check.source = FALSE)
Also, I notice this warning when I open the devtools library:
WARNING: Rtools 3.0 found on the path at c:/Rtools is not compatible with R 3.0.1.
Which is weird, Rtools 3.0 is suppose to be good from R >2.15.1 to R 3.0.x
Any ideas what is going on?
This is RStudio specific, as they wrap and/or changed a lot of functions from the utils for better integration. The problem lies with a call to getDependencies() to check for dependencies. But that function will also check whether the original package exists on CRAN and throws the given warning when it doesn't. A package you just built on your own computer is obviously not on CRAN, hence the warning.
In the source of the native install.packages(), getDependencies() isn't called in case you build from source or install from a different repository respectively. RStudio on the other hand calls getDependencies() before it passes everything on to the native install.packages() function.
This has to my knowledge no further effects, apart from confusing people. I didn't find a way to conveniently get rid of this in RStudio, as suppressWarnings() doesn't work in this context due to the complex way RStudio deals with this.
In a basic R console, you shouldn't have any problem.
So for the time being, I'd just ignore this and hope the RStudio team finds time to take care of this minor glitch.
