extract

I did a glm and I just want to extract the standard errors of each coefficient. I saw on the internet the function se.coef() but it doesn't work, it returns "Error: could not find function "se.coef"" . The information you're after is stored in the coefficients object returned by summary() . You can extract it thusly: summary(glm.D93)$coefficients[, 2] #Example from ?glm counts <- c(18,17,15,20,10,20,25,13,12) outcome <- gl(3,1,9) treatment <- gl(3,3) print(d.AD <- data.frame(treatment, outcome, counts)) glm.D93 <- glm(counts ~ outcome + treatment, family=poisson()) #coefficients has the data

I search for a long time how to extract frames from an animated GIF with PHP... unfortunaly I just found how to get their duration... I really need to extract the GIF frames and their duration to apply some resize, rotate, etc, on each and then to regenerate the GIF with edited frames ! I don't want to use any software, external library (like ImageMagick), just PHP: in fact I need to allow my class http://phpimageworkshop.com/ to work with animated GIF. If you have any idea, I'm listening you ^^ ! Sybio I spent my day creating a class based on this one to achieve what I wanted using only PHP!

I'm looking for a Java library to extract keywords from a block of text. The process should be as follows: stop word cleaning -> stemming -> searching for keywords based on English linguistics statistical information - meaning if a word appears more times in the text than in the English language in terms of probability than it's a keyword candidate. Is there a library that performs this task? sp00m Here is a possible solution using Apache Lucene . I didn't use the last version but the 3.6.2 one , since this is the one I know the best. Besides the /lucene-core-x.x.x.jar , don't forget to add

I want to extract the first word of a variable from a string. For example, take this input: <?php $myvalue = 'Test me more'; ?> The resultant output should be Test , which is the first word of the input. How can I do this? You can use the explode function as follows: $myvalue = 'Test me more'; $arr = explode(' ',trim($myvalue)); echo $arr[0]; // will print Test salathe There is a string function ( strtok ) which can be used to split a string into smaller strings ( tokens ) based on some separator(s). For the purposes of this thread, the first word (defined as anything before the first space

I want to extract all comments below a specific node within an XML document, using PHP. I have tried both the SimpleXML and DOMDocument methods, but I keep getting blank outputs. Is there a way to retrieve comments from within a document without having to resort to Regex? SimpleXML cannot handle comments, but the DOM extension can. Here's how you can extract all the comments. You just have to adapt the XPath expression to target the node you want. $doc = new DOMDocument; $doc->loadXML( '<doc> <node><!-- First node --></node> <node><!-- Second node --></node> </doc>' ); $xpath = new DOMXPath(

I have a string of HTML that I would like to check to see if there are any links inside of it and, if so, extract them and put them in an array. I can do this in jQuery with the simplicity of its selectors but I cannot find the right methods to use in PHP. For example, the string may look like this: <h1>Doctors</h1> <a title="C - G" href="linkl.html">C - G</a> <a title="G - K" href="link2.html">G - K</a> <a title="K - M" href="link3.html">K - M</a> How (in PHP) can i turn it into an array that looks something like: [1]=>"link1.html" [2]=>"link2.html" [3]=>"link3.html" Thanks, Ian Russell Dias
