This group is concerned with using R for corpus linguistics. Postings on loading & searching corpora with regular expressions & performing statistical/graphical analyses of corpus data are welcome. Also, this group will probably host the companion website of my intro to corpus linguistics with R.

hcfa questions
|
| |
Hi,
I have two basic questions regarding the use of hierarchical
configural frequency analysis.
First, is there a rule of thumb of how many factors are acceptable,
given a certain number of datapoints? To illustrate, I have around 350
examples and would like to analyze 5 factors (2-4 levels each). I... more »

Whole word matching
|
| |
Hi - a very simply question, but I'm hung up on it.
I have a vector (nouns) with a list of words I want to search for.
for (j in nouns){
output<-grep(j, student.lines.2, value=TRUE)}
This works, but it finds parts of words that match as well as whole
words. I need to limit it to whole words.... more »

Cosine matrix
|
| |
Hi.
Is there a way to get a matrix of cosines between vectors?
I have a 518 column vectors of length 2160 and I was hoping to get a
518*518 matrix of the cosines between these vectors.
Basically I would like to the equivalent of cor(mydata) but for
cosines not correlations between the vectors. But of course,... more »

rnorm function

I would like to have a detailed explanation of the rnorm function,
more complete than the one showed in help(rnorm). Where can I find it?
Thank you very much.

Odd numbers in simple graphics
|
| |
This could be a newbie question, but I canīt find information about it
on R manuals. This is my inquiry: How can I make a plot to show odd
numbers in an axis? This is for simple graphics, for example when
plotting two objects, a <- 1:10 ; b <- 11:20, I donīt get odd
numbers. Thank you very much.... more »

PlotLMER in LanguageR package
|
| |
Has anyone used this?
I can understand about 80% of what is in the LanguageR v0.95
documentation and the examples given there, but I am clearly missing
some critical aspects.
I want to plot the interaction of two continuous corpus frequency
variables, surface and morph, in the following model of lexical... more »

Combining two sets of data
|
| |
I have two sets of data I want to combine and analyse together in
linear mixed model. However data set two has one extra variable that
is a highly significant predictor and I can't seem to work out how to
combine the data sets taking into account the extra variable in data
set two.
Any help greatly received... more »

Boxplots with log-scaled y-axis: origin at 1
|
| |
Here is another question on odds ratios... I would like to diagram
them in a barplot in R. Benedikt (p.c.) assures me that they are best
shown when the y-axis is log-scaled - because disfavoring values are
all between 0 and 1, but favoring values can be anywhere above 1.
Log-scaling the y-axis seems to be no problem:... more »
