BMisc (version 1.4.10)

set_balanced_panel: set_balanced_panel

Description

In-place version of make_balanced_panel for large panels where copying `data` is undesirable. Converts `data` to a data.table by reference (mutating the caller's object into a data.table as a side effect, if it is not one already) instead of copying it. The balanced result must still be captured from the return value, the same as any other function in this package (filtering out unbalanced units cannot itself happen without allocating the smaller, filtered result somewhere).

Usage

set_balanced_panel(data, idname, tname)

Value

a balanced data.table

Arguments

data

data.frame (or data.table) used in function

idname

unique id

tname

time period name

Examples

id <- rep(seq(1, 100), each = 2)
t <- rep(seq(1, 2), 100)
y <- rnorm(200)
dta <- data.frame(id = id, t = t, y = y)
dta <- dta[-7, ]
dta <- set_balanced_panel(dta, idname = "id", tname = "t") # dta is now a data.table
