New RStudio image missing tzdata

[RobertJCarroll]

I was using the new RStudio image (0.0.3) and readr wasn't working- I was getting:

no Olson database found

Looks like the underlying image may not have tzdata installed, which means readr gets confused.

Thanks for reporting @RobertJCarroll, we can take a look.

readr works fine with the us.gcr.io/anvil-gcr-public/anvil-rstudio-bioconductor:0.0.5. Can you try that and let me know if you still have the issue?

And i'm unable to reproduce this issue with us.gcr.io/anvil-gcr-public/anvil-rstudio-base:0.0.3 as well.

I just spun up a new runtime with us.gcr.io/anvil-gcr-public/anvil-rstudio-base:0.0.3 and I am still getting this when I attempt to use readr::read_csv()

Error: Unknown TZ UTC
In addition: Warning message:
In OlsonNames() : no Olson database found
I made a very simple csv:
a,b
2020-05-01 12:00:00, asdf

It worked with us.gcr.io/anvil-gcr-public/anvil-rstudio-bioconductor:0.0.5.

I started up another on the rstudio base and it failed again.

It doesn't have the system dependency tzdata. That is the error, but the base image is supposed to be stripped down and light. I suggest you use the anvil-rstudio-bioconductor:0.0.5 image.

Is there any specific reason you want to use the base image?

[RobertJCarroll]

Ok, thanks. I can use the bioconductor moving forward

Re the image type, base:0.0.2 was what I saw recommended originally for RStudio in Terra, and it worked well. I swapped to the more recent version when I saw it was available. More generally, I don't need bioconductor. R + tidyverse gets most of what I need to use, so it seemed fitting, but if readr won't work due to missing system dependencies, I can go to something heavier weight.

I appreciate the help!
