Hi,
I hope you are doing well!

its packages. We also used some tutorials. We have words count limitation for
our paper. In early version of paper, I cited all packages in the reference

Your first check might be to see in the mean and sd are "reasonably"
close. Next approach would be to see if the `qqplot` of that vector has
an arguably straight-line relationship with a random draw from a Poisson

Hi Ahson,
Guessing what your data frame might look like, here are two easy ways:
All_companies<-data.frame(year=c(1970:2015,2000:2015,2010:2015),
COMPANY_NUMBER=c(rep(1,46),rep(2,16),rep(3,6)),
COMPANY_NAME=c(rep("IBM",46),rep("AMAZON",16),rep("SPACE-X",6)))
# easy ways

It's a good idea to specify both the things you are doing (which you
did) and the results you are getting, i.e. the exact error message

The following command:

Hello,
I have installed all packages successfully in order to unpack a source package.
I am still getting error when I run: install.packages ("package.tar.gz', repos

Is that possible my system doesn't allow Rstudio to compile some information in

What you are asking is one area where the package data.table really
shines. You didn't provide an example, but based on your question you
would do something like:
library(data.table)
dt <- as.data.table(All_companies)
dt[, .N, by=COMPANY_NAME]
You will have to read up on data.table, but .N gives

It occurs to me a simple table command will do what you say you want but I

Hello,
I've cc-ed the list.
Yes, I believe that generally speaking, POSIXct is better than POSIXlt.
POSIXlt is a complicated structure, POSXct is much simpler and gives
less problems. Datetimes are a problem because they are datetimes but
POSIXct is a good way of trying to make things simpler
As Bert says that does not look like R
