shinyapp deployment error | themes

[antoine4ucsd]

Hello Not sure if there is an easy fix but I created an app that works just fine locally with several nice echarts plot the deployment went welll but the app is not running online (error) I checked the log:

Error in value[[3L]]: Couldn't normalize path in `addResourcePath`, with arguments: `prefix` = 'shine-1.0.0'; `directoryPath` = '/Users/me/Library/R/x86_64/4.2/library/echarts4r/htmlwidgets/lib/echarts-4.8.0/themes'

is there a fix? it may have been addressed elsewhere but cannot find it. I used shine theme for most plots

thank you!

I think that was a bug in {htmlwidgets}, can you reinstall it and try again? Is it via shinyapps.io?

install.packages("htmlwidgets")

[antoine4ucsd]

trying now. thank you!

I added the above line in my code and specifically call the htmlwidgets library but this is still looking for a local path not sure how to handle this. really sorry

Where do you deploy this app?

The paths in there seems to be local paths on Windows machines...

[antoine4ucsd]

I agree . I am deploying the app from my laptop but it is submitted to shinyapps.io. I think I understand why now... I saved outputs that are called directly within the apps. bummer. I will have to go with a different strategy I guess. I will start from scratch and keep you posted. sorry for wasting your time. thank you!

[JohnCoene]

No worries but why are you storing plots locally? You should not need to do that, and even if you do you can make it work.

Use relative paths instead of normalised hardcoded path.

# good
./img.png

# bad
/User/me/img.png

[antoine4ucsd]

I know. I am not storing the plot itself but the RDS of the echart output. I think this is a stupid habit...

[antoine4ucsd]

I confirm that was it! may I ask one more thing... is there a way to increase the height of the echarts4rOutput generated with render renderEcharts4r? see for example:

I can increase the size of the box but not the plot itself. thank you for your patience.

Yes here: https://echarts4r.john-coene.com/reference/echarts4r-shiny

[antoine4ucsd]

wahoo. I just tried: I confirm it works. sorry for keeping you busy but it looks like nothing is impossible so far. thank you!
