R table - dynamic column name

Lucian — Mon, 28 Oct 2019 21:10:05 GMT

Hello,

I need a table visual in R for wich the name of a specific colum must get a value from a measure. I'm new to R but until now I could manage to rename a colum and obtain a new name using this code:

library(gridExtra) colnames(dataset)[colnames(dataset)=="TotalBase"] <- "NewName"

So the original name "TotalBase" was transformed into the "NewName".

But how could I pass a measure value?

Is it possible to achieve something like this?:

colnames(dataset)[colnames(dataset)=="TotalBase"] <- Table[Measure]

Kind Regards,

Lucian

Hello,

Unfortunately, I'm not an expert of R, however I can recommend you to investigate R code of other visuals to look for the answer, as this one, for instance.

Hi @v-evelk

And thank you for your time. Unfortunately I'm not an R expert too... 🙄 and the recommended code is way to complex to find a "clue" to solve my problem.

Maybe Microsoft will publish some tutorials specifically designed for R & Power BI... 😉

Kind Regards,

Lucian

Hi Lucian,

Technically, there aren't so many Power BI aspects in R code for R visual. Only a couple of them is reading of format panel options and buckets to build dataset.

In fact, to write R visual, you should know only R language.

If you want to figure out how to work with dataset, you should learn R, may be this and that articles will be useful.

Hello @v-evelk

Thank you for the recomended materials... There are good starting points in learning R.

Until then... I hope I will get enough votes on the Improved table visual - dynamic column names ideea so it would be implemented without needing R. 😁

Kind Regards,

Lucian
