Hello, I am writing cause I have a problem when try to create confidence envelopes in spatstat. I have a point data representing firms in my study area. When I try to create confidence envelopes the error message turns up: [> p <- envelope(point, fun=Kest, nsim=99) Error in marks.ppp(Y, dfok = FALSE) : Sorry, not implemented when the marks are a data frame] Could you write me how can I

Hi I'm working with the function Kest in the package SpatStat (under LINUX with R 2.1.0). In order to evaluate the statistical significance of my point pattern I'm doing 999 Montecarlo replications. The script that use the Kest function runs OK for most of the different point patterns that I have but for a particular point pattern, which have only 17 points, it runs until the 34th

Hi R users, This query is regarding the use of the 'envelope' function in Spatstat. My data can be represented as a point process with CONTINUOUS marks: points <- ppp(x=x,y=y, marks=m, window= wind) However the marks are alignments (lines), and so have to be treated differently to normal scalar marks. Hence to create a mcf object with the appropriate test function for alignment

Hi, I am trying to test the random labeling hypothesis with my data. I have a point pattern of bird nests and each nest has a mark that it is either predated or not-predated. I want to test the null hypothesis that the K distribution of predation events is equal to the K distribution of all events (nests). This is the code I am using: Kdif <- function(X,...,i) { Kidot <-

Hi I looked, but I didn't find it: I need an array [0 to 101] where each element is a list (the result of Kest in spatstat). I.e. I want to do: A[2] <- Kest(pp1) A[3] <- Kest(pp2) ... A[101] <- Kest(pp100) How can I create A ? Rainer -- Rainer M. Krug, Dipl. Phys. (Germany), MSc Conservation Biology (UCT) Department of Conservation Ecology University of Stellenbosch Matieland

Hello! I am writing you because I could not plot the confidence envelopes for functions Jest, Jcross, Jdot, Jmulti, and L, using the Spatstat package. I have already understood how to do that for Kest or Jest, that is: JEnv <- plot(envelope(PPPData, Jest)) Where PPPData is my ppp object. However, for Jcross I must specify the two marks I want to analyse. That is, usually I would get the

Hi--I'm trying to run a Ripley's K analysis on a point pattern within a window of 1 square km. The maximum distance I want to use is the diagonal of the window, around 1400m, run in 50m increments. The function defaults to a 250m maximum--I thought this was simply the way I had plotted it, but when I exported the data there was nothing over 250m. I've looked into seq and ginterval,

Hi Rowland and All, Can you answer 2 question below? 1. Does the host still able to share file to Windows, IOS and Android devices? 2. Does 74 kB of samba files is the typical file size be implemented in embedded device?

Hi I have the following loop and would like to vectorize it. Any ideas if it is possible? Thanks, Rainer Tha Loop: for (i in 2:Result$NoSims) { ppp <- runifpoint(Result$NoPlants) K <- Kest(ppp) Result$LSim[i,] <- sqrt(K$iso / pi) - K$r CM <- (Result$LSim[i,] * Result$LSim[i,]) / abs(K$r[2] - K$r[1]) Result$SigCM[i] <- sum(CM, na.rm=TRUE) print(i) flush.console() }

Hi All, May I have some advise on this issue? Thank you. On Fri, 27 Sep 2019 at 10:55, Hock Leong Ang <anghockleong501 at gmail.com> wrote: > Hi Sir/Madam/Miss, > > I am a firmware engineer.

Hi Rowland, The above files are built with AD DC. Without AD DC, the files size reduce from 186 kB to 74 kB. Without AD DC, the embedded device will act as a host. Questions: 1. Does the host still able to share file to Windows, IOS and Android devices? 2. Does 74 kB of samba files is the typical file size be implemented in embedded device? Thank you.

Hi Sir/Madam/Miss, I am a firmware engineer. I would like to implement file sharing between embedded device and android phone/ios phone/windows. I download the samba source code from https://github.com/samba-team/samba/tree/v4-11-stable with version v4-11-stable. I follow the instruction from link : https://wiki.samba.org/index.php/Build_Samba_from_Source to compile. I expected the compilation

Hi Rowland, Yes, the files I want should be in that folder : /usr/local/samba It is 186 kB, a very huge files. *Which is the compulsory files need for file sharing?* *Which files or sub-folder can I ignore?* Thank you. ubuntu at ubuntu-AngHL:/usr/local$ sudo du samba/ > [sudo] password for ubuntu: > Sorry, try again. > [sudo] password for ubuntu: > 56 samba/lib/security > 284

Hello, What are the minimum number of points in a point pattern before a clustering analysis using a Ripley K function loses any meaning? I haven't been able to find much comment in the literature about this --- instead case examples typically use 100-200 points as a minimum. Regards, Sebastian Pucilowski

Hi I have a loop which is doing time consuming calculations and I would like to be able to have some feedback on where it is in it's calculations. I tried to simply show the counter variable in the loop, but id doesn't work as all display seems to be delayed until the loop is completed. Is there any way of displaying the progress of a loop?

Hi All! As a new useR, I am currently working in R 2.5.1 to produce Ripley's L (the linear version of Ripley's K) for a spatial point dataset (originally a ESRI shapefile). I have coerced the data to a ppp object (because I was originally using 'kest' in the spstat package to produced Ripley's K) but I need to convert my spatial data to a spp object to be able to use

Also an option is to look here https://github.com/sahlberg/libsmb2 That might also help. There is more on this subject. Cifs/kernel (5.3) related. But i havent read into that.
