I want to compute the mean of a dataset. I tried it according to the introduction I got but it doesn't work.
I proceeded as follows:
mean(dataframe$column I want compute the mean of)
It was written that the object wasn't found.
I loaded the dataset before whilst clicking on "environment" and then "import dataset". However by "setwd" it didn't work. Maybe it has something to do with this.
The values in the respective column are all numbers by the way.
Does anybody know how this is solvable?
