I know it's possible to solve max e min problems by using these functions:
nlm, optimize, optim
but I don't know how to use them (...if possible...) to solve this problem.
I have a personal function called b_func(S) where S is an input array (1 X
n) and I'd like:
minimize mean(S) with 0
If I define my function that includes others internal functions, how can I
define the parameter's functions?
That is:
myfunc-function(y){...
func.int1- function(x){ sum(x}}
func.int2-function(z){funct.int1(z)^2} .
}
Is it possible to use func.int1 into
I import a dataframe composed by 2 variables and 14000 cases. Now I need the
labels of the cases sorted by the second variable V2, but if I sort the
dataframe according to the second variable:
mydataframe- mydataframe[order(mydataframe$V2),]
I notice that the labels are always the same (that is,
I think the question is discussed in other thread, but I don't exactly find

I'm working in Windows XP with 2GB of memory and a Pentium 4 - 3.00Ghx.
I have the necessity of working with large dataset, generally from 300,000
records to 800,000 (according to the project), and about 300
