With data.table, we can specify the .SDcols to select the ‘DR’ columns or ‘date_cols’ and assign back the output to those, then instead of using rowwise matching, use a row/column indexing to extract the values to create the ‘Result’ library(data.table) # get the column names that starts with DR dr_names <- grep(“^DR”, names(df1), value = … Read more
This is called string interpolation. It’s not a mystery, or a secret; there’s an entire section of the PHP manual dedicated to explaining it. C has printf that does a very similar thing: const unsigned int MAX_SIZE = 255; char variable[MAX_SIZE]; snprintf(variable, MAX_SIZE-1, “Var1 has %d value. Var 2 has %d value.”, var1, var2); In … Read more
