[R-es] Aplicar una función repetidamente

Hola a todos, Quisiera aplicar una función f(x) un total de k veces de manera recursiva. En pseudo código sería algo como Si k = 1, calcular f(x); Si k = 2, calcular f(f(x)); Si k = 3, calcular f(f(f(x))). Al final me gustaria tener una función g cuyos argumentos sean x y el valor de k. Así,

Hello, I have some code which was running in interactive mode while Rprof(..., line.profiling = TRUE). Near the end of my script, it opens up a pipe(..., open = "w") to a perl script, and at that point the execution gets stuck using 100% cpu. (The perl script itself never showed up in

Re: [R] physical constraint with gam

Hi again, I'm looking for some clarification on 2 things. 1. On that last note, I realize that s(x1,x2) would be the other obvious interaction to compare with - and I see that you recommend te(x1,x2) if they are not on the same scale. 2. If s(x1,by=x1) gives you a "parameter" value similar to a

[R] break string at specified possitions

Dear R-help I would like to split long string at specified precomputed positions. 'substring' needs beginings and ends. Is there a native function which accepts positions so I don't have to count second argument? For example I have vector of possitions pos<-c(5,10,19). Substring needs input

Hi Simon, Thanks for this explanation. To make sure I understand, another way of explaining the y axis in my original example is that it is the contribution to snowdepth relative to the other variables (the example only had fsca, but my actual case has a couple others). i.e. a negative s(fsca) of

Re: [R] Quantiles on multiply imputed survey data - mitools

Thanks for looking. No, for the quantiles it fails to instantiate the collection of designs correctly, whether hard-coding the variable name or using make.formula. 'with' passes make.formula correctly when calculating the mean, e.g. this works: MIcombine( with(des,

Re: [R] physical constraint with gam

The spline having a positive value is not the same as a glm coefficient having a positive value. When you plot a smooth, say s(x), that is equivalent to plotting the line 'beta * x' in a GLM. It is not equivalent to plotting 'beta'. The smooths in a gam are (usually) subject to `sum-to-zero'
