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,]))

Answer 2

Matrix are indexed by column so I am guessing you may just need to transpose your data and then construct a new matrix from it:

matrix(t(as.matrix(mydata)), nrow = 1)

Or you can convert it to a vector after the transposing depending on what you need:

as.vector(t(as.matrix(mydata)))
