Usage
lspec(X = NULL, flim = c(0,22), sxrow = 5, rows = 10, collev = seq(-40, 0, 1),
ovlp = 50, wl = 512, gr = FALSE, pal = reverse.gray.colors.2,
cex = 1, it = "jpeg", flist = NULL)
Arguments
X
data frame with results from manualoc function (or any data frame with columns
as in a manualoc output data frame). If given, two red dotted lines are plotted at the
start and end of a selection and the selections are labeled with the selection number
(an
flim
A numeric vector of length two indicating the highest and lowest
frequency limits (kHz) of the spectrogram, as in
spectro. Default is c(0,22). sxrow
A numeric vector of length one. Specifies seconds of spectrogram
per row. Default is 5.
rows
A numeric vector of length one. Specifies number of rows per
image file. Default is 10.
collev
A numeric vector of three. Specifies levels to partition the
amplitude range of the spectrogram (in dB). The more levels, the higher the
resolution of the spectrogram. Default is seq(-40, 0, 1).
ovlp
Numeric vector of length one specifyingconsecutive windows, as in spectro. Default is 50. High values of ovlp
slow down the function but produce more accurate selection limits (when provided, see X). wl
A number specifying the window length of the spectrogram, default
is 512.
gr
Logical argument to add grid to spectrogram. Default is FALSE.
pal
Color palette function for spectrogram. Default is
reverse.gray.colors.2.
cex
A numeric vector of length one giving the amount by which text
(including sound file and page number) should be magnified. Default is 1.
it
A character vector of length one giving the image type to be used. Currently only
"tiff" and "jpeg" are admitted. Default is "jpeg".
flist
character vector or factor indicating the subset of files that will be analyzed. Ignored
if X is provided.
