panel2cs takes a 2 period dataset and turns it
into a cross sectional dataset. The data includes the
change in time varying variables between the
time periods. 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
panel2cs(data, timevars, idname, tname)
Arguments
- data
data.frame used in function
- timevars
vector of names of variables to keep
- idname
unique id
- tname
time period name
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)
#> [1] 50
