R4.0 installation

[andrewjkwok]

Hi - A quick issue - I've been having problems installing veloviz with R4.0. However I'm getting messages saying that veloviz is not available for R4.0.0 regardless if I try installing via either bioconductor or devtools::install_github.

Is there any support for people not using R4.1?

Hi Andrew,

The R4.1 requirement is for compatibility with bioconductor's latest release. That being said, neither veloviz nor any of its dependencies require R4.1 so you can download the package, change the R version requirement in the description file then build and install the package from the local copy (see below).

Change DESCRIPTION file:
Depends:
R (>= 4.0)

Build package: (requires devtools and veloviz dependencies i.e. igraph, Rspectra.. see imports section of DESCRIPTION file):
library(devtools)
devtools::build("veloviz-package", binary = FALSE, vignettes = FALSE)

Install from source:
install.packages("veloviz_0.99.7.tar.gz",repos = NULL,type = "source")

Let me know if you still have issues.

Hi Lyla - I'm afraid I'm not sure how exactly to execute this. I tried cloning the github repository into my R 4.0 path and changing the DESCRIPTION file, but how do I build or install the package after that (or is it not the correct thing to clone the github repo?)? Also, when I try devtools::install.packages, it gives me the error:

Error: 'install.packages' is not an exported object from 'namespace:devtools'

I've never manually downloaded a package like this unfortunately so am a bit confused!

Hi Andrew,

I downloaded the repo as a zipped folder and unzipped it in a local directory:

To build the package, I used devtools::build as follows:
library(devtools)
devtools::build([path to unzipped repo], binary = FALSE, vignettes = FALSE).
For me, because I'm working in the same directory that contains the repo folder this was just devtools::build("veloviz-package", binary = FALSE, vignettes = FALSE)

To install, I did the following (there was a mistake in my previous comment, this isn't a devtools function):
install.packages([path to package .tar.gz file],repos = NULL,type = "source"). Again, if you're working in the same directory, it'll just be install.packages("veloviz_0.99.7.tar.gz",repos = NULL,type = "source")

Hope this works!

Yes - that has worked perfectly, thank you!
