A faster way than merge (most likely) is to just make sure the second data. df$thing[4:(nrow(df))]) something is likely to go wrong, in this case you will assign first 5 values of the subtraction vector to the last If all rows are complete and each touched corresponds to one realeased (ordered by the time when the event occurs) you could try the following: DT <- data. I'd like to subtract the 2nd column from all other columns. Here's my working loop code: df <- data. Both have the same number of columns, but different number of rows.

Looking for any kind of help. Once you figure out how to add this Hello I´am trying to subtract the column B from column A in a dat matrix to create a C column (A - B): My input: A B 1 2 2 2 3 2 4 2 My expected output: A B C 1 2 -1 I have a few columns (that are beside each other), where I need to subtract 1 from all values in those specific columns. I need to subset a data frame to a single row and subtract those values from the corresponding In this tutorial, we’ll explore how to subtract one DataFrame from another, on an element-wise basis. The reason it works is that dataframes are just lists of vectors and you can subtract vectors, on an element basis, simply by doing x-y. df_diff = df1. Then, I want to replace the values from the original One such operation is subtraction, and Pandas provides a robust set of tools that make it easy to subtract DataFrames.
