Extracting sentences with combinations of target words/terms from cancer patient text medical records
Hi Paul,
No need to collapse the information into a single text string, gregexpr() can take a vector of strings (sentences in your case). You can split your sentences up, number them how you want, then search for your pattern either via regex or via these extra packages you use which probably use the PCRE regex library anyway. However, as this is basically what you did, I'm not sure why

Extracting sentences with combinations of target words/terms from cancer patient text medical records
Hi Robert,
Thank you for your reply. An attempt to solve this via a regular expression query is particularly helpful. Unfortunately, I don't have much time to play around with this just now. Ultimately though, I think I would like to implement a solution something along the lines of what you have done. I have a book on regular expressions that I am now starting to read. In the meantime, the

sqlFetch doesn't read the whole objects.
Hi everyone,
I connected a data in FileMaker server with odbcConnect.
When I call the data "CANCERS" using sqlFetch, it looks okay.
However, the number of obs was different with the actual number.
If I read the same data from Microsoft Access, there are 656 obs. in it but
srt() shows me 600 obs.
Does anyone know why this happened and how to read all obs. from R?
Thank you in advance.

Apologies : question on transforming a table
Dear R-help list,
Apologies. I am trying to convert one table to another. It feels that it
should be a very straightforward answer with a single (or two) commands with
the right extensions, but I really can't figure this out right now. I have
several hundred pheno factors actually, so manually doing this line by line
is not an option.
My original table is approximately like this :

help on drawing right colors within a grouped xyplot (Lattice)
Hi,
I've lost my mind on it... I have to scatterplot two vectors, grouped by a third variable, with two different dimensions according to whether each cell line in the plot is sensitive or resistant to a given drug, and with a different color for each of 9 tissues of origin.
Here's what I've done:

why not? If so, why were the resources described there inadequate?

Extracting sentences with combinations of target words/terms from cancer patient text medical records
Hi Paul,
Sounds like you have your answer, but for fun I thought I'd try solving your problem using only a regular expression query and base R. I believe this works:

Extracting sentences with combinations of target words/terms from cancer patient text medical records
Hello All,
I need some help figuring out how to extract combinations of target words/terms from cancer patient text medical records. I've provided some sample data and code below to illustrate what I'm trying to do. At the moment, I'm trying to extract sentences that contain the word "breast" plus either "metastatic" or "stage IV".

Extracting sentences with combinations of target words/terms from cancer patient text medical records
Hi Bert,
Thanks for your reply. It appears that I didn't replace the variable name "sampletxt" with the argument "x" in my function. I've corrected that and now my code seems to be working fine.

"order" issue
Hi everybody, this is a real dummy thing.
I sorted a matrix based on a given column, and what I get is right, until it comes to columns of negative and positive values; than, "order" orders everything from max to min in the negative values, and then AGAIN from max to min in the positive values!!!
Why isn't everything order from max to min, and that's it?
Thank you!!!

fit data with skew t distribution
Hi,
Is there a function in R that I can use to fit the data with skew t
distribution? Speaking in detail, I first used the kernel density estimation
to fit my data, then I drew the skew t using my specified location, scale,
shape, and df to make it close to the kernel density. Now I want to get the
parameter estimations of the skew t which give me the closet density to the
kernel density.
