[R] y needing more than 2 functions

Dear all, I'm aware if y has two separate functions (depending on the conditions of x) you can use the ifelse function to separate y into two separate functions depending on input. How do you do this if there a multiple different conditions for x? for example, y fits the following between t>0 &

[R] Adding a migration element to a deterministic spatial model

Hi all, I've been working with a friend's model that is a spatial model consisting of 4 patches. She uses the code found below to add migration between the patches for the three species of concern. When I run a script incorporating this code, all four patches run independently without migration occ

[R] How does once import a function from an imported script?

and then enter B1 to see what the workspace returns, I get function(T1,t) (parms["B1"]) I am trying to get B1 to return as function(T1,t) {2*dnorm(T1(t),mean=32.5,sd=7)}, so that I can plot B1(T1,t). Is there any way to do this? Thank you for your assistance

[R] Plotting compound functions--help with defining x-axis as f(x)

Hi all, I'm having trouble locating a script that will allow to me to create graphs that show compound functions as a function of the simple function, rather than just x (or time as it is in my case). Currently I have the following functions defined in my script: > > > T1<-function(t) {27.5-12.5*

Hi all, My apologies if this message is incredibly inept but I am very new to both computer programming and to R. I am working with the odesolve add-on and have the following function defined RVF_Single <- function(t, x, p) within the script I also have the following functions defined: T1<-funct
