how to add the log of a variable to a dataset?

[Axebrif]

Hi everyone.
I'm pretty niew to R and I discovered R studio even more recently.
I'm trying to adapt a script from R (wich is working just fine in the R console) to R studio and the main issue I have is that it isn't creating a column with a mutated variable anymore with this line :
MetalsBC$LogBa <- with(MetalsBC, log(1+ Barium_Ba.))
this was running really well in RGui 3.6.1 without any package needed and doesn't compute on RStudio (I thought both were supposed to understand each others ^^)
thanks for your answers!

Barium_Ba.

Is there really a variable whose last letter of its name is the full stop symbol? or is that a typo?

Also if you have a specific error that you want help with, please consider sharing the error at a minimum, or do you mean, that you get no LogBa variable, but no error either ?

This has (almost certainly) nothing to do with RStudio or even the version of R you are using. Most likely you introduced an error in adapting your script.

To get help, please produce a reproducible example:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

A reprex to confirm that this works and that very likely you just have a typo

iris$log_sepal <- with(iris, log(1 + Sepal.Length))
head(iris$log_sepal)
#> [1] 1.808289 1.774952 1.740466 1.722767 1.791759 1.856298

thanks! That was simply it.
In the original dataset the variables names had differents symbols in it. I just simplified it and it's now running smoothly.
