Re: [R] Error messages using nonlinear regression function (nls)

Hi Thanks for the code but where is Prop? It is not a variable in germination data set so we do not know how you did the computation. My wild guess is, that your Prop do not follow logistic curve and therefore no results from nlsList Cheers Petr > -Original Message- > From: R-help [

Re: [R] dygraphs, multiple graphs and shiny

Answering my own question. It took a lot of trial and error, but the code below will work. The trick is to do form the lis to plots, create the html tag, and use renderUI() for that, and then in the UI.R part use htmlOutput() to output the result. -Roy > library(shiny) > > # Define UI fo

[R] dygraphs, multiple graphs and shiny

Hi All: This is really getting into the weeds, but I am hoping someone will have a solution. I am trying to use dygrahs for R, within Shiny. The situation arises when I am combining a number of dygraphs into one plot. If I am just in an RNotebook, if you look at: https://stackoverflow.com/q

[R] Error messages using nonlinear regression function (nls)

Hi all, I am trying to use nonlinear regression (nls) to analyze some seed germination data, but am having problems with error codes. The data that I have closely matches the germination dataset included in the drc package. Here is the head of the data temp species start end germinated TotS

Re: [R] creating tables with replacement

Dear David and Petr, It worked and I think now I can modify the code little bit to fit my requirement. Thank you so much for your help. Thanks, MW On Wed, Oct 18, 2017 at 7:15 AM, David L Carlson wrote: > Building on Petr's suggestion, you could modify his code to get all 10 > samples at once

[R] Problem with tq_mutate_xy() from the tidyquant package

I was able to reproduce the problem with this self-contained example. Maybe it could be reproduced with an even smaller one ... library(tidyquant) # Loads tidyverse, tidyquant, financial pkgs, xts/zoo library(xts) dtV <- as.Date("2017-01-01") + 1:100 locL <- list( foo=xts(rnorm(100), order.by=d

Re: [R] creating tables with replacement

Building on Petr's suggestion, you could modify his code to get all 10 samples at once in a compact format: > Samples <- lapply(lll, function(x) replicate(10, sample(x, rep=TRUE))) # Samples is a list containing 3 matrices, one for each group # Each column gives the index (row) numbers for a part

Re: [R] creating tables with replacement

Hi maybe there is another more elegant solution but something like this > idx <- 1:nrow(dat1) > lll <- split(idx, dat1$group) > dat1[unlist(lapply(lll, sample, rep=TRUE)),] gives you selected rows. You could use for cycle or save those data frames manually Cheers Petr > -Original Message-

[R] creating tables with replacement

Hi R User, I am new in R and trying to create tables with selecting rows randomly (but with replacement) for each group but each group should have same number as original. Is it possible to create it using the following example data set? Your help is highly appreciated. dat1<-structure(list(Regio
