Optimizing Data Manipulation with data.table: A Faster Alternative to Filtering and Sorting Rows with NAs
Optimized Solution Here is the optimized solution using data.table: library(data.table) # Define the columns to filter by cols <- paste0("Val", 1:2) # Sort the desired columns by group while sending NAs to the end setDT(data)[, (cols) := lapply(.SD, sort, na.last = TRUE), .SDcols = cols, by = .(Var1, Var2)] # Define an index which checks for rows with NAs in all columns indx <- rowSums(is.na(data[, cols, with = FALSE])) < length(cols) # Simple subset by condition data[indx] Explanation This solution takes advantage of data.
