[R] What the difference between .Golbalenv and package:base?

2014-08-24 Thread PO SU
Dear rusers,     As we know, there are a lot of environments in the search() path, such as   .Golbalenv and package:base . And  i can just use  .Golbalenv$a ,.Golbalenv$b to use the virable,  but i must use as.envrionment("package:base") to find virable, i feel it not very convenient. For e

[R] adaptivetau with time-dependent rate "parameters"; non-autonomous population dynamics via Monte Carlo

2014-08-24 Thread Rainer K. SACHS
I am interested in "non-autonomous" population dynamics. The simplest example is the deterministic ode of exponential growth or decay of a cell population with average size s(t)>0: ds/dt=M(t) s. Here M(t), instead of being constant, is an explicit function of time and is independent of s, as can oc

You replied only to me. But I'm replying to you directly and the r-help list as well. Hopefully someone there will be able to help you with this statistical methodology. Please remember that I'm very ignorant of statistics (I made a C in it in college). Your reply did seem quite understandable to m
