[R] help with r package "trip"

Hi List, I'm relatively new to R, so apologies if my question is rather elementary. I'm working with some bird tracking data and I would like to calculate the maximum distance traveled from the colony. For the maximum distance traveled, I was going to use the function homedist(). However,

Re: [R] processing time too long

I'm still unsure of what you are attempting to do with this data. First, it is very sparse, appearing to be the counts of occurrences of 2567 strings, some of which are recognizable English words. I suspect that you are trying to get something very simple like the frequency of these strings within

Re: [R] processing time too long

Hi Sashi, Since I do not want to create a large fake data set and then painstakingly test and debug your code, why not try your code with a subset of the data, maybe only 400 rows. If that runs slowly, your code is very inefficient (it looks as though it is). You can then begin to identify where

Hi JI, The most likely problems are negative numbers for sd or "k" being larger than the number of mu.m2 or disp.m2 values. Jim On Wed, Jun 15, 2016 at 4:06 AM, JI Cho wrote: > Dear R users, > > I have been using rnorm, rbinom and have been getting the following warning >

Do not believe everything you read on the internet! "In one of the resources I found in over the internet explains that the mean and sd should be declared as integers." That is compete crap. The mean of a norma/Gaussian can be any real; the sd can be any positive real. Moreover, one does not

Your log showed that g++ was given the flag -std=c++0x. It should be -std=c++11 so the 'using typename = blahblah' syntax works. Either your feather/src/Makevars is missing the line CXX_STD=CXX11 or your version of R is lacking support for CXX_STD. > g++ -m32 -std=c++0x

It is a "warning" message, but not an "error" message. Therefore, you should still get parameter estimates. However, lack of convergence is often an important issue. Although in the case of the EM algorithm, it may not be so serious since EM is notoriously slow to converge when you set a

Hi Greg, This is obviously a problem with the data. The first error indicates that the sequence of integers regrange[1]:regrange[2] is too long to be allocated. Most likely this is because one or both of the endpoints are infinite. Maybe if you can find where the NAs are you can fix it. Jim On
