Following up from my question here, I am trying to replicate in R the functionality of the Stata command duplicates tag, which allows me to tag all the rows of a dataset that are duplicates in terms of a given set of variables:. Value. The pivoting spec allows us to be more precise about exactly how pivot_longer (df, spec = spec) changes the shape of df: it will have nrow (df) * nrow (spec) rows, and ncol (df) - nrow (spec) + ncol (spec) - 2 columns. Otherwise, the filter approach would return all maximum values (rows) per group while the OP's ddply approach with which. the matrix is organized so that first column is the lower number of the pair, and. To build your own unique random number generator in Excel, you will need to chain several functions together like shown below. n^n - worsens near-exponentially estimated from Stirling's formula). One possible solution which avoids repetitions of the same pair as well as different orders is using the data. frame(a = 1:3, b = 5:7) c <- 9:10 how to create a new data frame that is the combination of df and c without expanding df:Reshape long to wide with two columns to expand in R data. The fastest way to do this is by double-clicking the fill handle:Select Group by on the Home tab. If you use mutate() with a regular data frame, it computes the mean of x, y, and z across all rows. grid(). For a simple example, a <- c (1,2,3,"X","Y","M") b is identical as b.
