Arguments

visual

visual systems. Options are:

  • 'none': no visual sensitivity data.

  • 'all': all visual sensitivity data.

  • 'apis': Honeybee Apis mellifera visual system.

  • 'avg.uv': average avian UV system.

  • 'avg.v': average avian V system.

  • 'bluetit': Blue tit Cyanistes caeruleus visual system.

  • 'canis': Canid Canis familiaris visual system.

  • 'cie2': 2-degree colour matching functions for CIE models of human colour vision. Functions are linear transformations of the 2-degree cone fundamentals of Stockman & Sharpe (2000), as ratified by the CIE (2006).

  • 'cie10': 10-degree colour matching functions for CIE models of human colour vision. Functions are linear transformations of the 10-degree cone fundamentals of Stockman & Sharpe (2000), as ratified by the CIE (2006).

  • 'ctenophorus': Ornate dragon lizard Ctenophorus ornatus.

  • 'musca': Housefly Musca domestica visual system.

  • 'pfowl': Peafowl Pavo cristatus visual system.

  • 'star': Starling Sturnus vulgaris visual system.

  • 'habronattus': Jumping spider Habronattus pyrrithrix.

  • 'rhinecanthus': Triggerfish Rhinecanthus aculeatus.

achromatic

the sensitivity data used to calculate luminance (achromatic) receptor stimulation. Options are:

  • 'none': no achromatic sensitivity data.

  • 'all': all achromatic sensitivity data.

  • 'bt.dc': Blue tit Cyanistes caeruleus double cone.

  • 'ch.dc': Chicken Gallus gallus double cone.

  • 'st.dc': Starling Sturnus vulgaris double cone.

  • 'md.r1': Housefly Musca domestica R1-6 photoreceptor.

  • 'ra.dc': Triggerfish Rhinecanthus aculeatus double cone.

illum

illuminants. Options are:

  • 'none': no illuminant data.

  • 'all': all background spectral data.

  • 'bluesky' open blue sky.

  • 'D65': standard daylight.

  • 'forestshade' forest shade.

trans

Ocular transmission data. Options are:

  • 'none': no transmission data.

  • 'all': all transmission data.

  • 'bluetit': blue tit Cyanistes caeruleus ocular transmission (from Hart et al. 2000).

  • 'blackbird': blackbird Turdus merula ocular transmission (from Hart et al. 2000).

bkg

background spectra. Options are:

  • 'none': no background spectral data.

  • 'all': all background spectral data.

  • 'green': green foliage.

plot

should the spectral data be plotted, or returned instead (defaults to FALSE)?

...

additional graphical options passed to plot.rspec when plot = TRUE.

Value

An object of class rspec (when plot = FALSE), containing a wavelength column 'wl' and spectral data binned at 1 nm intervals from 300-700 nm.

Examples

# NOT RUN {
# Plot the honeybee's receptors
sensdata(visual = 'apis', ylab = 'Absorbance', plot = TRUE)

# Plot the average UV vs V avian receptors
sensdata(visual = c('avg.v', 'avg.uv'), ylab = 'Absorbance', plot = TRUE)

# Retrieve the CIE colour matching functions as an rspec object
ciedat <- sensdata(visual = c('cie2', 'cie10'))
# }
