Plots one or multiple spectral curves in the same graph to rapidly compare groups of spectra.

explorespec(rspecdata, by = NULL, scale = c("equal", "free"),
legpos = "topright", ...)

## Arguments

rspecdata (required) a data frame, possibly an object of class rspec that has wavelength range in the first column, named 'wl', and spectral measurements in the remaining columns. number of spectra to include in each graph (defaults to 1) defines how the y-axis should be scaled. 'free': panels can vary in the range of the y-axis; 'equal': all panels have the y-axis with the same range. legend position control. Either a vector containing x and y coordinates or a single keyword from the list: "bottomright", "bottom", "bottomleft", "left", "topleft", "top", "topright", "right" and "center". additional parameters to be passed to plot

## Value

Spectral curve plots

## Note

Number of plots presented per page depends on the number of graphs produced.

## Examples

# NOT RUN {
data(sicalis)
explorespec(sicalis, 3)
explorespec(sicalis, 3, ylim = c(0, 100), legpos = c(500, 80))
# }
