piecewise: creates a Piecewise object.

In alvarofranq/piecewise: A package to handle piecewise models

Description

Create a piecewise object

Usage

piecewise(models = NULL, condition = NULL, ...)

Arguments

models	A list with the models.
condition	A character vector with the conditions to use each model.
...	Other arguments

Examples

require(piecewise)
set.seed(0)
df_01 <- data.frame(x = 1:5, y = (1:5)+rnorm(5,0,1))
mod_01 <- glm("y ~ x", data = df_01)
con_01 <- "x >= 0 & x < 6"

df_02 <- data.frame(x = 6:10, y = (5:1)+rnorm(5,0,1))
mod_02 <- glm("y ~ x", data = df_02)
con_02 <- "x >= 6 & x <= 10"
p <- piecewise(models = list(mod_01 = mod_01, mod_02 = mod_02),condition = c(con_01, con_02))

# get fitted values for each model
fitted(p)

# predict some values
newdata <- data.frame(x = 1.5)
predict(p, newdata = newdata)
