Fix: attempt to set ‘colnames’ on an object with less than two dimensions

When performing data manipulation in R, developers and analysts often encounter cryptic error messages that halt progress. One particularly confusing issue, especially for those transitioning from spreadsheet tools, involves incorrectly assigning metadata to data structures. This guide focuses on diagnosing and resolving a specific, common runtime issue: Error in `colnames<-`(`*tmp*`, value = c(“var1”, “var2”, “var3”)) […]
