[R] How to compare the fitting of function?

Hello, I have fitted two curves to the data. How can I tell which one is more fitted? By eye (see plot underneath) I would say that the function Gompertz is better than the function Holling type III; how can I give a number to this hunch? This is an example: ``` # functions holling = function(a, b,

And since this is about RNA expression data, you would do better posting on the Bioconductor Help site rather than here. You are more likely to find the expertise and interest you seek there. Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things in

Re: [R] algorithms that cluster time series data

Hi, Unsupervised classification (clustering) is a huge field. There's an entire task view devoted to it, where you can see many of the large array of R packages that perform some sort of clustering. https://cran.r-project.org/web/views/Cluster.html Since that is an overwhelming list, you may be

[R] algorithms that cluster time series data

Dear all, please may I ask for a suggestion regarding the algorithms to cluster the expression data in single cells (scRNA-seq) at multiple time points : we do have expression data for 30 000 genes in 10 datasets that have been collected at multiple time points, and i was wondering if you could

Re: [R] National Weather Service Data

I am trying to access National Weather Service forecasting data through the rNOMADS package. I’m not sure if the Weather Service software – grib2 – loaded correctly. Second, some of the examples in the rNOMADS documentation seem to run correctly but I’m not sure what the output means. Any anv

Re: [R] how to calculate odd ratios with R?

Dear Luigi You could try the epitools package which gives a large number of ways of doing this. I would have thought that using Wald intervals for the log odds ration was not optimal with small frequencies. Michael On 06/07/2020 14:01, Luigi Marongiu wrote: Hello, Is it possible to calculat

Re: [R] how to calculate odd ratios with R?

Luigi, Odds ratios can be produced using a logistic regression, which can be performed using the glm function. The following has a detailed description of how logistic regression can be performed using R: https://stats.idre.ucla.edu/r/dae/logit-regression/ John John David Sorkin M.D., Ph.D. P

[R] how to calculate odd ratios with R?

Hello, Is it possible to calculate with a single function the odd ratios?

Re: [R] [External] challenging data merging/joining problem

Hi Christopher, This seems pretty standard and straightforward, unless I am missing something. You can do the "full join" without changing variable names. Here's a small code example with two tibbles, a and b, where the column 'x' in a corresponds to the column 'u' in b. a <- tibble(x=1:15,y=21:35
