[R] R help- fit distribution "fitdistr"

Hello, I just start using R. I want to use ??fitdistr?? to fit distribution of the data. Then how can I verify if the data really fit the distribution? Thanks [data is attached] res<-fitdistr(data$Report.delay, "Poisson") h<-hist(data$Report.delay) xfit<-floor(seq(0, 250, 50))

Re: [R] Computing means of multiple variables based on a condition

These will be overlapping subgroups from the same data frame. For example, d<=2 will have length=9, d<=4 will have length=7, etc. Ken kmna...@gmail.com 914-450-0816 (tel) 347-730-4813 (fax) > On May 25, 2016, at 9:06 PM, William Dunlap wrote: > > Just to be clear, do

Re: [R] Computing means of multiple variables based on a condition

Just to be clear, do you really want your 'condition' groups to be be subsets of one another? Most (all?) of the *ply functions assume you want non-overlapping groups so they do a split-summarize-combine sequence. You would have to replace the split part of that. Bill Dunlap TIBCO Software

Re: [R] mixed models

Please keep the mailing list in the loop by using reply-all. I don't think there is a requirement that the number of levels is equal, but there may be problems if you don't have the minimum number of records corresponding to each combination of levels specified in your model. You can change

Re: [R] strange error

It may not be the problem, but with RStudio this error pops up when the area reserved for plotting is too small. Typically this area is in the right hand column, if you have this minimised (perhaps to maximise space for typing) you will hit this problem. Try making it bigger. Edit: Just ran your

You forgot to show the commands to us that you used to read the data in with (your example is not "reproducible"). This step can make all the difference in the world as to whether your analysis commands will work or not. -- Sent from my phone. Please excuse my brevity. On May 25, 2016

Re: [R] Reduce does not work with data.table?

This is a design feature of data.table objects, which don't conform to the normal functional programming paradigm that R is usually designed to adhere to and which Reduce expects. Specifically, they normally modify in-place rather than leaving the original object alone. In short, don't do

Reduce is failing when applied to a list of elements of class data.table. Perhaps this is a bug? Example: library(data.table) dt1 <- data.table(x = 1:3, y = 4:6) dt2 <- data.table(x = 4:6, y = 1:3) dt3 <- data.table(x = 0:-2, y = 0:-2) # This works fine dt1 + dt2 + dt2 #x y # 1: 5 5 # 2:
