Tidyverse methods for bioRad objects, currently only select is implemented. When dplyr or tidyverse is loaded the select method can be used to select parameters.
select.scan(.data, ...)if (require(dplyr, quietly = TRUE)) {
# locate example volume file:
pvolfile <- system.file("extdata", "volume.h5", package = "bioRad")
# load the file:
example_pvol <- read_pvolfile(pvolfile)
pvol_selected<-select(example_pvol, DBZH, ZDR)
# Only selected parameters are retained in the pvol
get_scan(pvol_selected, 1.5)
# Also a series of parameters in a scan can be selected
select(get_scan(example_pvol, 2.5), VRADH:ZDR)
}
#> Polar scan (class scan)

#> parameters: VRADH RHOHV ZDR
#> elevation angle: 2.5 deg
#> dims: 480 bins x 360 rays
