Yes I got the warning message from 'glm' and ignored it, I will never do it again. On the other hand, I think that including the 'weights' argument improved the results ( I don't get a warning message anymore) and now they are closer to the SPSS results, thought they are not exactly the same

[R] R copies for no apparent reason

Hi Everyone, Some R function will make R copy the object AFTER the function call, like nrow, while some others don't, like sum. For example the following code: x = as.double(1:1e8) system.time(x[1] <- 100) y = sum(x) system.time(x[1] <- 200) ## Fast (takes 0s), after calling sum foo

Re: [R] Fw: Averaging without NAs

Hi Elahe, You can do so using the mean function, mean(), by specifying an additional argument, na.rm = TRUE. In this case, you specify that you wish to remove (rm) all NA values in the columns. —> mean($X2016.Q1, na.rm = T). By default, na.rm is set to FALSE, so mean() will return a NA value.

Well, you read documents from directory = "D:/Shivi/R Project" and you say that you have 220+ files in this directory If you move respective files into some working directory you could use let say docs<- Corpus(DirSource(directory = "D:/Shivi/R Project/work")) without need to use setwd. But

It comes from linearizing log(x) around the fitted value, derivative of log is 1/x, so aa$se.fit/aa$fit == bb$se.fit For diverged estimates, this gets dubious as the linearization only works in a neighborhood and for x not too close to the singularity of log() at zero. -pd > On 02 Mar 2017,
