[R] Cannot run install binary package on Windows 8
Hi all, I am just starting with R and cannot use lmtest package on Windows 8. This package contains dwtest function that I am interested in. I began with installing the core of R (with rgui) - version 3.1.3 64-bit. Then I installed lmtest package using GUI menu, but after success message I cannot run dwtest() getting message that the it cannot find the function. When I used installed.packages() function I saw lmtest on the list but there was yes under the NeedsCompilation column. Does it mean I need to compile the package in order to use it? I uninstalled lmtest and tried to put binary Windows version by downloading zip file from here: http://cran.r-project.org/web/packages/lmtest/index.html I took the file: http://cran.r-project.org/bin/windows/contrib/3.1/lmtest_0.9-33.zip downloaded it and tried to use the function of installing from local zip file. However the effect was the same: NeedsCompilation set to true, dwtest does not work. The package contains binary file for 64-bit (DLLs). What can I do in order to run this? __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

I wish to remove people's names and also their initials which are peppered throughout the corpus. But, because some people's initials are the same as parts of common words - e.g. 'am' = 'became' = 'bec e' or 'ec' = 'because' = 'b ause' or 'ar' = 'arrival' = 'rival' (which has a completely different meaning). Is there any way of doing this without leaving a trail of nonsense half-terms behind? I suspect that it might have something to do with regular expressions, but to be honest, I'm (currently) pretty crap with those. Would it make a difference if I removed initials and names *prior* to converting all text to lower case, so I remove 'AM' and because 'became' is lower case, it should remain unaffected? Any recommendations on how best to proceed with this? Thanks as always.

Re: [R] multiple input files single output - lapply? - pls advise
Hi Ista
This works brilliantly and is so elegant!
Yes, i googled quite a while but did not come across do.call till now.
Thanks again

Hi Bernard,
Did you try searching for an answer? This question (minus the xts part
which I don't think will matter) has been asked and answered many times,
with
do.call(rbind, foo)
being a common answer.
Best,

Dear R users,
hope you can point me in the right direction. I am stuck with the
following
problem.
My function f1 reads csv files, manipulates them into the right xts
format and returns the output at the end. This works perfectly fine. Now,
I
need to run f1 over a long list of various csv files, all of the same
format, but different dates (or time stamps) which is guaranteed by
design.
All these individual results per each file I hope to combine into one xts
or zoo object.
I tried lapply as follows:
# all csv files start with z1:
file.names - list.files(pattern = z1*, full.names = T, recursive =
FALSE)
# my function:
f1 - function(x, param){
# x: the csv file
# param: some parameter for calculation
# spits results out
return(results)
}
res - lapply(file.names, function(x){f1(x, param)})
I wrote the output to res and by subsetting res[1], res[2], ... I can
retrieve the results of each individual csv file on which I applied my
function f1.
How could I append or merge all individual results res[i] for my i csv
files into one xts or zoo object?
Many thanks in advance,
Bernard

Re: [R] Removing words and initials with tm
Hello Sun, The order of the TM transformations makes a lot of difference. It isn't a shortcut, but if you identify all names you could create your own Stop words list: corpus -tm_map(corpus , removeWords, c(english, )) In the case of York, Key Word in Context (KWIC) syntax could be used to check how certain words are used. You could identify the words useages you want to remove or retain and respectively rename the relevant instances. This is labour intensive, but Greis in his Quantitative Corpus Linguistics, notes that sometimes time spent on trying to refine code might be better spent on manual analysis (p164). This book includes a KWIC type function (page 127), but I haven't been able to work out how to modify it to read more than six words either side of the specified word. Six should be adequate for your purpose. Jockers book also includes a KWIC function but I don't believe it searches the entire corpus, rather a specified text. I recently checked and TM doesn't have a KWIC function, but for the R talented (which excludes me) it might be possible to write one. For example, Jim Holtman once wrote a KWIC function to identify word use in a csv file.

Re: [R] Cannot run install binary package on Windows 8
You need to load the library after you have installed the package. Only libraries in the base R installation load automatically. Thus every time you want to use contributed package XXX you need to issue the command library(XXX) or require(XXX) So at the top of your program try library(lmtest) You should be good to go. Newbies often miss this step.
