In lemna: Lemna Ecotox Effect Model

lemna 1.0.2, 2025-03-31

• Default value of parameter beta modified due to typo in previous report versions, now conforms with Klein et al. (2025), report version 1.2 (to be published); new value: beta=0.25, old value: beta=0.025.
• Default value for deSolve's parameter hmax set to hmax=0.01.
• Effect calculation is no longer bound to the interval ]oo, 1], instead the full range of rational numbers is possible.
• Internal concentration C_int can no longer become negative in R equations.
• Verification vignette is pre-knitted to reduce built time of the package. See directory vignettes/orig/ for the original RMarkdown file.
