Error in R-recipe to generate dataset

Hello,

I run 3 lines of code to produce a dataset in R and expose it to DSS. However, it gives an error I don't understand. Do you have any idea why this is happening?

Error log:


[14:41:40] [INFO] [dku.utils] - > library(dataiku)
[14:41:41] [INFO] [dku.utils] - > mydata <- data.frame(a=c(0,1,2),b=c(0,1,2),c=c(0,1,2))
[14:41:41] [INFO] [dku.utils] - > dkuWriteDatasetSchema(mydata,"test_r_dynamic_in")
[14:41:41] [INFO] [dku.utils] - Error in parsed$detailedMessage :
[14:41:41] [INFO] [dku.utils] - object of type 'externalptr' is not subsettable

Many thanks,

Cameron

    Hi Cameron,

    Using `dkuWriteDataset` will write the schema and the dataset:


    library(dataiku)

    r_test <- data.frame(name = c('jed','bob'), age = c(12, 5))

    # Recipe outputs
    dkuWriteDataset(r_test,"r_test")

    Hi Jed,

    Thanks for the reply. I get the same error (see below). Also, it is using deprecated code.
    To reproduce, I:
    Click on +RECIPE/Code/R.
    Add an output named r_test.
    Click on CREATE RECIPE.
    Copy paste your code, then save.
    Exit to flow diagram, click on the r_test glyph.
    Click Build.
