Applying a function across variables in JASP

  Hi Bob,

  Thanks for the question. We’re working on the interface to make row manipulations in JASP more intuitive. To do what you’d like in the current version of JASP, we have to resort to the R interface in compute column. The R code is then 

  apply(data.frame(Q1, Q2, Q3), 1, mean, na.rm=TRUE)

  or 

  apply(data.frame(Q1, Q2, Q3), 1, sd, na.rm=TRUE)

  Hence, it is possible to do this in JASP, but it requires some knowledge of R syntax, which is not as user-friendly as we’d like. We hope to have the new data manipulation interface implemented soon. 

  Cheers,

  Alexander

  I am wondering if this function has been added. I am new to JASP and trying to understand how to compute a single mean from multiple columns (a scale). The R code gives me blank answer, I assume because there is a missing variable somewhere). Is there another way to do this?

  Have you confirmed that your variables are not nominal? Maybe you could send along a small part of your data set (or some made up values) as a .jasp file so we can give it a go?
