velocity_dp function

Velocity plot of a view object

velocity_dp(obj, add_mean = TRUE, vscale = 5, maxpts = 10000, alpha = 0.5, ...)

Arguments

• obj: View object.
• add_mean: add the mean to each line? (default is TRUE).
• vscale: a vertical scaling to apply to the plot (default is 5).
• maxpts: maximum number of points to plot.
• alpha: ggplot aesthetic value.
• ...: passed to ggplot2::geom_point(),

Returns

a ggplot object.

Examples

r1 <- get_sample_recording()
rv1 <- get_raw_view(r1, "Central", "", "Sitar")
pv1 <- get_processed_view(rv1)
dp <- c("LWrist", "RWrist", "LElbow", "RElbow", "LEye", "REye", "Neck", "MidHip")
fv1 <- apply_filter_sgolay(pv1, data_point = dp, n = 41, p = 4)
sub_fv1 <- subset(fv1, Time >= 10 & Time <= 20, by = 2)
velocity_dp(sub_fv1)
