In BMisc: Miscellaneous Functions for Panel Data, Quantiles, and Printing Results

Panel Data to Repeated Cross Sections

Description

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

Value

data.frame

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)
