search for: boudary

Hi: I have a question about the R plot, I change the size of the y axis label from 1 to 2, but part of the word is missing as being cut. So I guess it is over the boudary of the R graphical setting. Would you please help me with it? How to change the boundary so that the full part of my y axis label will appear? Your help is highly appreciated! sincerely hang No pain no gain.

Hi, I have a scalar valued function with several variables. One of the variables is restricted to be non-negative. For example, f(x,y)=sqrt(x)*exp(y), then x should be non-negative. I need the gradient and hessian for some vector (0,y), i.e., I need the gradient and hessian at the boudary of parameter space. The "numderiv" package does not work, even for f(x)=sqrt(x), if you do "genD(f,x=0)", warning message comes out. I need the one sided derivatives. Thanks if you could provide some help. -- View this message in context: http://www.nabble.com/Any-numeric-...

Can someone please help me understand the examples given in the dwt function of the waveslim library library(waveslim) ?dwt I'm having a problem understanding these lines. I assume they are required because of how the algorythm deals with the signal bounderies. Am I correct in thinking that for wavelets of scale 1 and 2, the coefiecints need to be shifted by 2 places, for scale 3 and 4 shift

Dear R users, I used to "OPTIM" to minimize the obj. function below. Even though I used the true parameter values as initial values, the results are not very good. How could I improve my results? Any suggestion will be greatly appreciated. Regards, Kathryn Lord #------------------------------------------------------------------------------------------ x = c(0.35938587,
