adeptdata

The goal of adeptdata is to host the data used in vignettes for adept R package.

Installation

# install.packages("devtools")
devtools::install_github("martakarass/adeptdata")

Example

acc_running is a sample raw accelerometry data collected during 25 minutes of an outdoor run. Data were collected at frequency 100 Hz with two ActiGraph GT9X Link sensors located at left hip and left ankle. See ?acc_running for details.

stride_template is a list containing walking stride pattern templates derived from accelerometry data collected at four body locations: left wrist, left hip, left ankle, and right ankle. See ?stride_template for details.

template <- list(stride_template$left_ankle[[2]][1, ],
                 stride_template$left_ankle[[2]][2, ])
par(mfrow = c(1,2), cex = 0.7)
plot(template[[1]], type = "l", xlab = "", ylab = "", main = "Left ankle: template 1")
plot(template[[2]], type = "l", xlab = "", ylab = "", main = "Left ankle: template 2")
