[R] spatstat installation

2020-04-14 Thread Mauro Pedone
Hello ,
I am trying the spatstat package installation
on R 3.3.0

the package is spatstat_1.63-3.tar.gz
,the OS is oracle enterprise linux 7

at the end I receive the error
Error : .onAttach failed in attachNamespace() for 'spatstat', details:
  call: if (today - as.Date(rdate) > 365) {
  error: missing value where TRUE/FALSE needed

ask to the community if someone encountered this problem.

thanks and regards

Mauro

Re: [R] Integrate inside function

Dear David and Micheal,
thanks for your suggestion. Vectorize does what I need.
David you suggest me that I didn't built the function in a manner that 
would vectorize. Could you please explain me what's wrong?

[R] Integrate inside function

2012-03-15 Thread Mauro Rossi

Dear R users,
first I take this opportunity to greet all the R community for your 
continuous efforts.
I wrote a function to calculate the pdf and cdf of a custom distribution 
(mixed gamma model).

The function is the following:

pmixedgamma3 <- function(y, shape1, rate1, shape2, rate2, prev)
{
density.function<-function(x)
{
shape1=shape1
rate1=rate1
shape2=shape2
rate2=rate2
prev=prev
		fun<-prev*((rate1^shape1)/gamma(shape1)*(x^(shape1-1))*exp(-rate1*x)) 
+ (1-prev)*((rate2^shape2)/gamma(shape2)*(x^(shape2-1))*exp(-rate2*x))

return(fun)
}
den<-density.function(y)
p.mixedgamma<-integrate(f=density.function,lower=0,upper=y)
return(list(density=den,cumdensity=p.mixedgamma$value))
}

Why doesn't this calculate cumdensity (p.mixedgamma) in case x is a vector?

For instance try:
pmixedgamma3(c(10,20),shape1=10,rate1=1,shape2=10,rate2=1,prev=0.5)

As you can see cumdensity is calculated just for the first x value.

Thanks in advance
Best
Mauro

[R] How can I do these simulations with R code

2011-08-22 Thread Mauro Sznelwar
1) The Pareto P(alfa) distribution is defined by its density f(x|alfa) 
=alfa*X^(-alfa-1) over (1 to infinity). Show that it can be generated as the 
-1/alfa power of a uniforme variate. Plot the histogram and the density.
2) The Poisson distribution P(lambda) is connected to the exponential 
distribution through the Poisson process in that it can be simulated by 
generating exponential random variables until their sums exceeds 1. That is, if 
Xi~Exp(lambda) and if K is the first value for which summation(i=1 to k+1)Xi>1 
então K~P(lambda). Compare this algorithm with rpois.
3) Se U e V are i.i.d U[0,1], the distribuiton of 
(U^1/alfa)/((U^1/alfa)+V(1/beta)), conditional on U^1/alfa+V^1/beta<=1, is the 
beta(alfa, beta) distribution. Compare this algorithm for both small and large 
values of alfa and beta.

[R] perspective plot

2011-05-05 Thread Mauro
Hello,

I`m tryint to plot some variable over x and y coordinate, but can`t figure
out hot to do it ( I could do a simple scatterplot3d, but there I can`t
change the viewing angle). 

My dataset looks something like this (dataframe):

X   Y   Q95
21 2628711 1104437 0.7723994
22 2628721 1104437 0.5961789
23 2628731 1104437 1.2013182
24 2628741 1104437 1.3468632
25 2628751 1104437 1.1035517
26 2628761 1104437 1.0528809

Is there a way to plot Q95 over x and y? Something like persp(x,y,z) would
be nice, but can`t figure out the right input format for this function.


Thanks a lot,

Mauro

[R] Integrate na.rm in own defined functions

2011-04-20 Thread Mauro
It`s probably an easy question, but couldn`t figure it out.

I`ve defined a function like: 

rmse<-function (x){
dquared<-x^2
sum1<-sum(x^2)
rmse<-sqrt((1/length(x))*sum1)
rmse}

My problem is, that I have NA Values in x and the above function returns NA.

I`m looking for a way to use "na.rm=TRUE" like in for instance
mean(x,na.rm=TRUE).

Does anybody know how to do this?


Thank you very much.

[R] help on stepfunction

2011-02-08 Thread Mauro Ferreira
Dear members,

I would like a help for extracting the values from a step function
(stepfun).

>From help(stepfun) we have the following example:

Y0<-c(1.,2.,4.,3.)
y0<-c(1.,2.,3.,4.)
sfun<-stepfun(1:3,y0,f=0)
plot(sfun)

Now, suppose instead I was given the object (*sfun*, say) from which I
wanted to extract the values generated by the function *stepfun*. More
precisely, I want to know how to get the X and Y (generated by the function
*sfun*) that are used in the graph (plot(sfun)).

Thanks in advance for helping me.

   Dear all
   How can I obtain the data from the function "rearrange" in package quantreg
   More especifically, based on the example below (available in the help of the

   "rearrange(zp)" ?
   data(engel)
z <- rq(foodexp ~ income, tau = -1,data =engel)
zp <- predict(z,newdata=list(income=quantile(engel$income,.03)),type="stepfun")

[R] Neyman Scott rainfall pulse model

2008-11-12 Thread Mauro Rossi

Dear R user,
   I'm looking to use a stochastic model for rainfall generation. This 
can be done with the Neyman-Scott Random Pulse (NSRP) model (see e.g. 
Cowpertwait, P. S. P., C. G. Kilsby, and P. E. O'Connell (2002), A 
space-time Neyman-Scott model of rainfall: Empirical analysis of 
extremes, Water Resour. Res., 38(8), 1131, doi:10.1029/2001WR000709).

Does anyone have any R code or suggestions for it?

Thank you in advance.

[R] distribution fitting

2008-10-23 Thread Tortonesi Mauro
Dear R-help readers,

I am writing to you in order to ask you a few questions about
distribution fitting in R.

I am trying to find out whether the set of event interarrival times
that I am currently analyzing is distributed with a Gamma or General
Pareto distribution. The event arrival granularity is in minutes and
interarrival times are in seconds, so the values I have are 0, 60,
120, 180, and so on...

Here is what I did. Since several values of the interarrival_times
array are zero, to avoid numerical errors when calculating their
logarithm, I set them to 1E-10:

> # fix numerical values
> for (i in 1:length(interarrival_times)) {
+   if (interarrival_times[i] == 0)
+   interarrival_times[i] = 0.01
+ }

Then I defined the negative log likelihood for the Gamma distribution:

> nll_gamma_log <- function(lambda_log, alfa_log) {
+   n <- length(interarrival_times)
+   x <- interarrival_times
+   -n*exp(alfa_log)*lambda_log + n*log(gamma(exp(alfa_log))) -
(exp(alfa_log)-1)*sum(log(x)) + exp(lambda_log)*sum(x)
+ }

and passed it to the mle function:

> est_gamma <- mle(minuslog = nll_gamma_log, start = list(lambda_log = 0, 
> alfa_log=0))
There were 50 or more warnings (use warnings() to see the first 50)

of course I got many "value out of range" warnings:

> warnings()
Warning messages:
1: In log(gamma(exp(log_alfa))) ... : value out of range in 'gammafn'
[...]
7: In gamma(exp(log_alfa)) ... : NaNs produced
[...]
50: In log(gamma(exp(log_alfa))) ... : value out of range in 'gammafn'

but that was expected, right?

The real problems come out when I try to fit a General Pareto
distribution. Using the same method, I calculated the negative log
likelihood function for the General Pareto distribution:

> # negative log-likelihood function for general pareto distribution
> nll_gpd <- function(xi, log_sigma, mu) { # shape, scale, location
+ n <- length(interarrival_times)
+ x <- interarrival_times
+ cat("xi:",xi,"; log_sigma:",log_sigma,"; mu:",mu,"\n")
+ n*log_sigma + (xi+1)*sum(log(1+xi*(x-mu)/exp(log_sigma)))/xi
+ }

and passed it to the mle function. However, this time I get some errors:

> est_gpd <- mle(minuslog = nll_gpd, start = list(xi = 1, log_sigma = 1, mu = 
> 1))

I really don't know how to fix this problem. Do you have any suggestions?


Thank you very much in advance.

[R] S.O.S.

2008-08-19 Thread Mauro Belleggia
Hi, My name is Mauro Belleggia, I m doing an ANOSIM (using "vegan" package)
to test statistically whether there is a significant difference between 3
(1,2 and 3) groups of sampling units. My results were:

Call:
anosim(dis = distancias, grouping = Lt)
Dissimilarity: bray

ANOSIM statistic R: 0.1313
  Significance: < 0.001

Based on  1000  permutations

Empirical upper confidence limits of R:
   90%95%  97.5%99%
0.0331 0.0464 0.0569 0.0693

Dissimilarity ranks between and within classes:
0%25%50%75%   100%N
Between  2 950.75 1786.5 2641.5 3402.5 2220
1   13 958.50 1927.0 2660.5 3402.5  595
21 629.50 1318.0 2050.5 3258.0  435
3   10 356.00  840.0 1599.0 3367.0  153

I know that there where dissimilarities among grops but i can t interpret
between which. 1 Vs 2?, 2 Vs. 3? Or 1 Vs. 3?

I will be very very greatful with you.
Looking forward to getting your prompt response.

[R] Number -> Fraction

2007-09-13 Thread Mauro Arnoldi
Hi everybody!
I'm new to this list and also to the R program.

I'd like to know if there is a function able to convert results into 
Fractional form like my scientific calculator have. For example:

> 1/3
[1] 0.333

> function_that_return_a_fraction_from_numbers(0.333)
[1] 1/3

Thanks

Mauro
