Re: [R] R help - Web Scraping of Google News using R

What you are doing wrong is both trying yourself and asking others to violate Google's Terms of Service and (amongst other things) get your IP banned along with anyone who aids you (or worse). Please don't. Just because something can be done does not mean it should be done. On Tue, May 24, 2016

Re: [R] Mixed model analysis

This has nothing to do with R, per se. This is a statistical issue. You need to work with a statistician, as your statistical background is inadequate (google "mixed effects models") if you really need this. Cheers, Bert On Tue, May 24, 2016 at 7:27 PM Neny Sitorus

Re: [R] Sprintf to call data frame from environment

Hi Beatriz, I'll guess that you have a number of files with names like this: Samples_1.txt Samples_2.txt ... Each one can be read with a function like read.table and will return a data frame with default names (V1, V2, ...). You then want to extract the first element (column) of the data frame.

Re: [R] Sprintf to call data frame from environment

It is not clear (at least to me) what your actual task is. But, if Samples_1.txt is the actual name of a data frame that exists in memory (and not a filename), then you need to wrap the sprintf() in a get() function. get(sprintf("Samples_%s.txt", 1))$V1 I am no expert on "computing on the

Re: [R] identify duplicate entries in data frame and calculate mean

Don't see that as being a big problem. If your data grows then dplyr supports connections to external databases. Alternately if you just want a mean, most databases can do that directly in SQL. On Tue, May 24, 2016 at 4:17 PM, Matthew wrote: > Thank you very

Re: [R] identify duplicate entries in data frame and calculate mean

You have several options. 1. You could use the aggregate function. If your data frame is called DF, you could do something like with(DF, aggregate(Length, list(Identifier), mean)) 2. You could use the dplyr package like this library(dplyr) summarize(group_by(DF, Identifier),

I have a data frame with 10 columns. In the last column is an alphaneumaric identifier. For most rows, this alphaneumaric identifier is unique to the file, however some of these alphanemeric idenitifiers occur in duplicate, triplicate or more. When they do occur more than once they are in
