While still early in development, IronRuby is taking advantage of the Dynamic Language Runtime (DLR) to create an implementation of the Ruby language on top of the CLR. With IronRuby, you can employ existing Ruby apps and frameworks together with the .NET Framework and .NET-compliant languages...
Goal: Acquire information on the authors of this package. We can use other filters such asdisplay_nameandhas_orcid: authors_from_names<-oa_fetch(entity="authors",display_name=c("Massimo Aria","Jason Priem"),has_orcid=TRUE)authors_from_names|>show_authors()|>knitr::kable() ...
When functions such asrxDataStepare used to create database tables that havevarcharcolumns, the column width is estimated based on a sample of the data. If the width can vary, it might be necessary to pad all strings to a common length. ...
Thissandboxapproach imposes some restrictions on the R scripts running in the Power BI service, such as accessing the Internet, or accessing other resources that aren't required to create the R visual. R scripts error experience When an R script encounters an error, the R visual isn't plotted...
