To achieve the second dataframe, I first created an empty dataframe with the same amount of rows of df, then with a for loop cbind the first two rows of the dataframe (because they do not need any manipulation) and with the index add the next ones after calculated the difference. Let's say I have 4 vectors, each with 4 elements that go from 1 to 16 sequentially. The test also performs the same calculation for , and then calculates a Pearson goodness of fit statistic. frame columnwise into a mids object. # create matrix with 4 columns and 4 rows data= matrix (c (1:16), ncol=4, byrow=TRUE) # specify the column names and row names of matrix colnames (data) = c ('col1','col2','col3','col4') rownames (data) <- c. 行の追加であれば "rbind"、列の追加であれば "cbind" という関数を使う ことができます.
