How to combine all rows into a single row in R? [closed]

Answer 1

We can get the transpose and concatenate to a vector. Note that the transpose converts to a matrix and there is no need to call as.matrix.

as.vector(t(mydata))

Or we can use unlist after splitting the rows into a list.

unlist(lapply(seq_len(nrow(mydata)), function(i) mydata[i,]))
