Re: [R] Logistic Regression output baseline (reference) category

Hi, I have now read an introductory text on regression and I think I do understand what the intercept is doing. However, my original question is still unanswered. I understand that the intercept term is the constant that each other term is measured against. I think baseline is a good word for

Re: [R] Question about Imager

Hi, I can't answer your collage question but I am very glad that you brought imager to my attention - it looks great. That said, you might give ImageJ or its cousin Fiji a look for the task you have. There are hundreds of examples and a nice (easy!) macro language coupled to the user

Re: [R] Manually inserting an extra tick on the y axis in ggplot2

Thanks. Actually, found a good answer online - I wanted a horizontal line with a y intercept of 12.6. I set m <- 12.6 I drew the line with geom_hline then added geom_text(aes(0,m,label = m, vjust = -1)) which worked just fine. Ken kmna...@gmail.com 914-450-0816 (tel) 347-730-4813 (fax)

You might abe able to do it by using scale_y_continuous() but it would be a great help to see some (minimal) code and some sample data. Please have a look at http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and/or http://adv-r.had.co.nz/Reproducibility.html

Re: [R] Persistent state in a function?

Here is the rough equivalent to what you did but using the R6 package: library(R6) Cache <- R6Class("Cache", public = list( myCache = numeric(0), add = function(x) { self$myCache <- c(self$myCache, x) print(self$myCache) } ) ) cacheThis <- Cache$new()

Re: [R] Persistent state in a function?

To follow on, for the record, here's the code example using local() instead: Comments appreciated. # === CODE cacheThis <- local({ # creates a closure, assigned to "cacheThis" myCache <- numeric()# a persistent variable in the closure's environment useCache <-

I can't tell what's happening here unless I see the actual code that produces the behaviour. Just the code should be fine, no need to attach your big file. Also: what exactly is the issue you need to solve? B. On Mar 25, 2016, at 6:39 AM, Jun Chen wrote: > Hello:

Hi Jennifer, This is very hacky, but I think it does most of what you want. I can't really work out what "Sample Size" is supposed to be: MOERS<-data.frame(MOE[MOE$SEX_P=="Males_0.1",c("Meff","Proportion")], Males_0.1=MOE[MOE$SEX_P=="Males_0.1","MOE"],

You could make a vector with all possible IDs. Use %in% to get just those that are missing. missing.id <- c (101:1000) missing.id <- missing.id[! missing.id %in% s $ID] Df2 <- data.frame(ID = missing.id, CODE = paste0 (PDT, missing.id), VAR = 0) Modify your original data.frame so you can rind
