Hello, I had some code that used to work but it must have been for a previous version of Julia. I can’t find what I am looking for in the DataFrame docs Getting Started · DataFrames.jl I want to replace values in an array or DataFrame that are less than 0.5 to 0.0. QWER = rand(5, 5) QWER[QWER .>= …

Yes, if you want to change all of the columns, then use QWER .= ifelse.(QWER .> 0.5, 0.0, QWER)

How to replace/set/change value in array/dataframe if value is less/greater than?

Thank you for your reply - you are correct, the arrays solution works.

Does the DataFrames on not just specify the first column (assuming it is named col1)?
