Hello, I'm working in spatstat and having difficulty with the ppp objects. I can get a ppp object for one set of data, but with the same code applied to a second data set (all I am changing is the field identifier), I get the following error message: Error in switch(w$type, rectangle={: internal error: some total scores are neither 0 nor 1 Any thoughts on what this means and how to correct

Hello all. I am trying to create one figure, divided into 6 graphs/plots each with an inset sub-figure. I can use to layout command to generate one figure with one inset sub-figure, but cannot seem to do it for multiple figures on one page. I've tried a test with the following code: layout(matrix(c(1,2,3,4), nrow=2, byrow=TRUE)) plot(rnorm(10), rnorm(10)) plot(rnorm(10), rnorm(10))

Hello, I'm using library(spatstat) and trying to use ppp on my dataset. I get a segmentation error when I try to run it. Any suggestions? Code below ...

Hello all, I'm attempting to conduct spatial analysis of trees within a plot. I want to see if the trees are spatially correlated to soil characteristics, say pH, or moisture content. I think one way to do it is with mpl, however, my soil characteristics were not taken at exactly the same locations as my trees and further, the vectors aren't the same length. I'm getting the

Hello. I think this is a simple problem. I have R running a program which generates variables that it 'remembers'. The trouble is that I've modified the file that it's generating these variables from but doesn't seem to realize that. When I type 'trees' - I get the same data set produced. I tried shutting R down and not saving the workspace, but when I open 'er

Hi Everyone, I have a question regarding the construction of 3D graphs in 'R', BUT these graphs also need to illustrate movement (with time) of the prostate gland (using radiological techniques). I am not sure how to do this in 'R' although I'm sure there is some way of doing it. Below, I have copied and pasted some of the data with which I'm working on. The data

Hello All, I have a simple question based on how things are labeled on my heat map; particularly, there is this annoying "X" that appears before the numeric value of all the labels of my columns. Let's say I have the following silly data, stored in "temp.txt" 1905 1910 1950 1992 2011 2020 Gnat 0.08 0.29 0.29 0.37 0.39 0.43 Snake

Dear Members of the R-Help, While using a R function - 'aggregate' that you developed, I become to have a question. In that function, > aggregate(x, by, FUN, ..., simplify = TRUE) I was wondering about what type of FUN I should write if I want to get "the most frequent value of the subgroup" as a summary statistics of the subgroups. I will appreciate if I can get

Resending .... Also, related feedback - I got no "permission to post this list is only for list members" notification from Mailman in response to my first post to this list so I did not know the mail was discarded. Would be very nice to attend to that setting in Mailman so folks know that their post never made it through vs. assuming folks are busy and will get back to you shortly.

Hello, I still can't figure out why my users' passwords are expiring. Ever since we switched to LDAP, passwords expire every 14 days.

I have a dataset called "raw-data" . I am trying to use the following code - col_name<-names(raw_data) for (i in 1:(length(names(raw_data))-2)) { tbl=table(raw_data$Pay.Late.Dummy, raw_data$col_name[i]) chisqtest<-chisq.test(tbl) } Say the 1st column of my raw_data is Column1. The idea is when i=1 then raw_data$col_name[i] will automatically become raw_data$Column1 ,

I'm trying to insert rows of a data.frame into a database table, or update where the key fields of a record already exist in the table. I've come up with a possible solution below, but would like to hear if anyone has a better solution. # The problem demonstrated: # Create a data.frame with test values library(RODBC) tbl <- data.frame( key1 = rep(1:3, each = 2), key2 =

(As a noob to R, this is my first posting - yes yes, groans all around...) I'm trying to extract certain rows from a data frame. I used the following to import data from a CSV txt file. data <- read.table(file="data.txt", header=TRUE) when I do this, my attempt to extract the data rows only from where the Station value equals 1? data.station1 <- data[data$Station == 1]

Hi, I am facing the problem that I want to plot a histogram chart set freq to true and overlay with normal or weibull or exponential distribution curve.
