Description Usage Arguments Details Author(s) Examples

Similar to python zip, 'vzip' takes input vectors and merges them together by their input order and index. A simple example is two numeric vectors, A = c(1,1,1) and B = c(2,2,2). The output of vzip(A,B) would simply be a single vector of c(1,2,1,2,1,2). Any number of vectors can be input, but each input vector must be of the same length. Output vector class depends on input vector consensus.

1 2	vcollapse(d) vcollapse(d, sep = "-", fill = "NA")

`d`	data.frame or matrix or object coercible to a matrix. Row contents will be combined into a single output vector.
`sep`	character used to separate collapsed contents.
`fill`	character used to fill empty values within the coerced object.

vcollapse returns a single vector from input data.frame or matrix where row contents have been combined or collapsed, as with 'paste(..., collaspe = "")'.

df <- data.frame(
  "A" = letters[1:5],
  "B" = 3:7,
  "C" = LETTERS[2:6])
vcollapse(df)
vcollapse(df, sep = "-")
vcollapse(df, sep = "-", fill = "z")
