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 (

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

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.

You seem to be confusing R and RStudio. The latter is an IDE + more
for the former, which is open source statistics and data analysis
software (+ more). The details you show above are for R, not RStudio.
They are entirely separate.

Hi Hugh,
I believe the recommended way of saving ggplots is through ggsave. It
defaults to take the latest plot displayed, but you can specify which plot
to save by passing the variable to the plot argument.
If you need to save multiple plots in one file, you have to create a
multipage plot using

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
Hi Pikal,

Hi
Hmm, if you need only three files why not copy them to another directory and
use the same command for reading them from that other directory.
You probably could do this from R itself however I am almost sure that doing
this task by OS is far less complicated.

The question seems easy but I could not find an answer for it. I have the
following column in my data frame and I want to take average of the column
excluding the number of NAs.
$X2016.Q1 : int 47 53 75 97 NA NA 23 NA 43 NA
Does anyone know how to do that?

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.
