The previous article introduced the sensitivity and elasticity to seasonal matrix model of imaginary annual plant. Both sensitivity and elasticity are partial derivatives. This means the values can only predict … Continue reading
The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. In this article, let’s try the sensitivity analysis of these matrices and the … Continue reading
The previous article introduced the seasonal matrices and the population growth rate λ of imaginary annual plant. This article focuses on the meaning of the eigenvector at first, and then … Continue reading
Let’s challenge to build a matrix population model of annual organisms and then calculate the population growth rate λ using R. Consider a simple life cycle of imaginary annual plants; … Continue reading
The boxplotdbl 1.2.2 and the diaplt 1.2.1 are listed at CRAN. Now the procedure to install, load and use the package is: install.packages(‘boxplotdbl’) library(boxplotdbl) f <- as.factor(rep(1:2, each=5)) boxplotdou(f, rnorm(10), … Continue reading
This article describes changes from the first release on March 2013, including changes from the beta release of package boxplotdbl.
