subsample_file: Feature-based subsampling of signals from a file
In jiho/soundclass: Signal classifier for sounds

Description Usage Arguments Value See Also Examples

Read a tab or space delimited file containing signal characteristics and subsample a given proportion of signals

1	subsample_file(file, p, k = 10, plot = TRUE)

`file`	path to a tab or space delimited file containing signal characteristics
`p`	proportion of the total number of signals to subsample, between 0 and 1
`k`	number of groups
`plot`	wether to plot the result of the subsampling

Two files, one for the signals picked in the subsample and one for the non-picked signals

subsample

# get an example file from within the package
data_file <- system.file("sirena.txt", package="soundclass")
# check what it looks like
file.show(data_file)
# copy it to a temporary directory in which we can work
tmp <- tempdir()
file.copy(data_file, tmp)
# perform feature based subsampling on this file and show the results
subsample_file(paste0(tmp, "/sirena.txt"), p=0.2)
list.files(tmp)
