The default functionality is to keep all the variables from period 1 and add all the variables listed by name in timevars from period 2 to those.

Usage

Value

data.frame

Arguments

data

data.frame used in function

timevars

vector of names of variables to keep

idname

tname

Examples

id <- rep(seq(1, 50), 2)
t <- rep(seq(1, 2), each = 50)
y <- rnorm(100)
dta <- data.frame(id = id, t = t, y = y)
out <- panel2cs(dta, timevars = "y", idname = "id", tname = "t")
nrow(out)
