6 R data.table symbols and operators you should know

Hi please make a drilldown maps with highcharter package. Thanks so much

I ran the same code as before in an R script and had no issues. That suggests that there may be an issue with running data.table in Quarto on a Mac.

[@haraldurkarlsson1147]

I ran the code inside RStudio's Quarto and I am hoping that is not what is messing up data.table.

[@haraldurkarlsson1147]

Excellent presentation that sets the standard we have all become used to from Karen. Data.table is a great package but as a Mac user I continually run into issues when running it. That does not appear to the a problem on Linux or Windows. Why don't the developers fix these issues for Mac users?

is there a reason that the .() was necessary for the Avg salary calculation rather than just haivng usd[, AvgSalary = mean(ConvertedComp), by = Language]

[@IDGTECHtalk]

The .() is optional when only one column is involved but used if you are dealing with more than one column. It’s my habit to use it for single columns also so my syntax is consistent. --Sharon
