Hi Thilini,
It is fairly simple in R once you have imported the data. Say you have
a data frame obtained by exporting the Excel table to CSV and then
importing it with "read.csv". I'm not sure whether you have a number
in each cell or just a 0/1 absent/present value, but it may not
matter. Assume t
Assuming that the input is x <- 1:4, try this one-liner:
> embed(c(0*x[-1], x, 0*x[-1]), 4)
[,1] [,2] [,3] [,4]
[1,]1000
[2,]2100
[3,]3210
[4,]4321
[5,]0432
[6,]0043
[7,]0004

If you read your data into R, it is simple to compute the percentages. Use Save
As in Excel to save your data as a .csv (comma separated variables) file. Then
use read.csv() to create a data frame in R as Jim indicated. Put it in the
default directory that R is using (this depends on what operat
Dear all,
I was using R version 3.3.2 to install devtools and some other packages in

Microsoft Azure Machine Learning Studio environment.
Now, since Azure works with CRAN R version 3.1.0, I decided to download

Change the "4" in embed(c(0*x[-1], x, 0*x[-1]), 4) to length(x) and it will
generalize to other length vectors. This solution is not as compact, but it

The code you have attached (if you replace 00 by 50) generates two sets of 50

mass 1/50. Do the following to get a plot of t

Is it really necessary for you you use such an antiquated version of R just
because your computer is old? (I don't use Macs, but that is not necessarily so
for other operating systems.)

Hi R users,
I'd like to ask that where to find the 'lubridate' package for Mac Sierra?
I downloaded one version for OS X Mavericks binaries, but it does not work.

Or if there is another way to get '', 'mm', and 'dd' from time variable

Huh?
I just installed the Mavericks binary on my OSX Sierra without problems:
install.packages("lubridate", repos='https://cran.revolutionanalytics.com')
A google search would have found this essentially instantly!
As for native R functions for parsing dates: of course!

Thanks a lot for the feedback, Dirk and Mehmet,
My (large) test-code is in RUnit and so I'm glad to hear that it is fine.
RUnit worked very well for me and I do not have a reason to switch.
