You can install the released version of TrendLSW from CRAN with:
install.packages("TrendLSW")You can install the development version of TrendLSW from GitHub with:
devtools::install_github("https://github.com/EuanMcGonigle/TrendLSW")For detailed examples, see the help files within the package. We can generate a small example for performing trend and spectrum estimation as follows:
library(TrendLSW)
set.seed(1)
noise <- rnorm(512) * c(seq(from = 1, to = 3, length = 256), seq(from = 3, to = 1, length = 256))
trend <- seq(from = 0, to = 5, length = 512)
x <- trend + noiseApply the TLSW function:
