Hello I'd like to create a simple topological map of a river system, ie all the waterways, where they join and points on them such as gauging stations so that it looks something like the London Tube map - where distances are not important but the relationships of the nodes are. I could probably Heath-Robinson something together but I wondered whether there was any kind of package already out

Hello I've successfully installed the package "Detpack" and remembered to call it via library() But when I try to use the functions i get this: chi2testuniform(vals, 0.05) Error in chi2testuniform(vals, 0.05) : could not find function "chi2testuniform" And yet this function (amongst other which also are not recognised) are all listed on the CRAN page:

Hello Does anyone know how to get the p values for changepoints in the "changepoint" package? There is guidance in the CRAN vignette https://cran.r-project.org/web/packages/changepoint/changepoint.pdf but I can't make it work to get the p value out... Thanks Nick Wray [[alternative HTML version deleted]]

Hello does anyone know how to set the confidence level within the seqMK() function in the pheno package. It seems to be set automatically at 0.05 and there seems to be neither an input function to set a different level, as there are with some changepoint functions, nor an output to give one the p-value of the changepoint identification which you get with functions ie func$p_value etc ... Thanks

Hello I am using k medoids in R to generate sets of clusters for datasets through time. I can plot the individual clusters OK but what I cannot find is a way of pulling out the co-ordinates of the individual points in the cluster diagrams - none of the kmed$... info sets seems to be this. Beneath is an example of a k medoid prog using the built in US arrests dataset - this is not the data I am

Hello The other say I posted a question about altering confidence limits in the seqMK() function in the pheno package. I didn't get any bites but in any case I've been trying to use this function. It seems to me to give very odd results - sometimes identifying 8 or 9 changepoints in a relatively short vector of maybe 40 elements, and at other times not giving any changepoints at all,

Hello I am testing for the homogeneity of clusters of (yearly) seasonal data using the rao.test from the circular package. I can't find anywhere (including the Cran pages) which specifically mentions the null hypothesis for this test. Playing around with it, for example using say the toy code beneath it would seem that the null is that the data sets tested are not homogenous, which is fine

Hello - does anyone know whether there are any packages for Mann-Kendall mutation tests in R available? The only one I could find online is this MK_mut_test: Mann-Kendall mutation test in Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel. (rdrr.io) <https://rdrr.io/github/Sibada/sibadaR/man/MK_mut_test.html> but there doesn't seem to

Hello I have a palette vector of colour blind colours (in hexadecimal) which I?m using for plots, but they are not see-through, and as I wanted to overlay some histograms I wanted to convert these colours to rgb, when you can set the opacity. I have found the function col2rgb(), which works in the sense that it gives a vector of numbers but these don?t work directly in rgb because they are too

Hello - I am trying to plot flows in a number of rivers within the same plot, and need to colour the lines differently, using a colour-blind palette. Code beneath works but has colours assigned by the program I have made some simple dummy data: ## code 1 cb8<- c("#000000", "#E69F00", "#56B4E9", "#009E73","#F0E442", "#0072B2",

R help email Hello I?m trying to work my way through the rnrfa package RJ-2016-036.pdf (r-project.org) <https://journal.r-project.org/archive/2016/RJ-2016-036/RJ-2016-036.pdf> I?ve got it loaded OK and can access the data by the catalogue() command - gives me a tibble with names, grid refs etc allStations <- catalogue() allStations This works OK But when I try to run the example

Hello I have lots of folders of individual Scottish river catchments on my uni One Drive. Each folder is labelled with the river name eg "Tay" and they are all in a folder named "Scotland" I want to list the folders on One Drive so that I can cross check that I have them all against a list of folders on my laptop. Can I somehow use list.files() - I've tried various things

Hello As a postgrad I have been helping an undergraduate student with R coding but she has a problem with R studio on her laptop which I can't fix - basically when she runs a plot it appears without a y axis label with the black line plot frame hard against the plot window and the bottom of the plot, where you would expect to see the horizontal axis and the x axis label etc is completely
