I’m going over the array tutorial trying to see how to add 1 to the content of an array but am having difficulties. I do not want to replace the contents of the column by 1, but add 1 to the value already in the column. What is the correct way to do this for an array and dataframe? QWER = rand(5, 5…

[image] HelgavonLichtenstein: QWER = rand(5, 5) QWER[:,2:4] .+1 Try QWER[:,2:4] .+= 1 This is a shorthand notation for QWER[:,2:4] = QWER[:,2:4] .+ 1

How to add/subtract values in a dataframe or array column?
