Tools to estimate tongue length, foraging distance and body weight form bees intertegular distances (IT).
You have to install the package from GitHub. Thats easy:
install.packages("devtools")
require(devtools)
install_github('ibartomeus/BeeIT')
library(BeeIT)
Once the package is loaded, its use is pretty simple, it require a vector of intertegular distances (IT) and bee families.
#dummy dataset
its <- rnorm(100, 10, 2)
families <- rep(c("Andrenidae", "Apidae", "Colletidae", "Halictidae", "Megachilidae"),20)
Out <- ITconverter(IT = its, family = families)
plot(Out$tongue_length.tongue ~ Out$body_mass)
You can ask for help
?ITconverter
?ITtongue
?ITforaging
?ITweigth
Or access the data used to fit the equation:
data(tongues)
head(tongues)
?tongues
And cite our paper if you use it:
