  • How to name variables on the fly in R?

    - by Maiasaura
    Is it possible to create new variable names on the fly? I'd like to read data frames from a list into new variables with numbers at the end. Something like orca1, orca2, orca3... If I try something like paste("orca",i,sep="")=list_name[[i]] I get this error target of assignment expands to non-language object Is there another way around this?

  • Stuck at being unable to print a substring no more than 4679 characters

    - by Newcoder
    I have a program that does string manipulation on very large strings (around 100K). The first step in my program is to cleanup the input string so that it only contains certain characters. Here is my method for this cleanup: public static String analyzeString (String input) { String output = null; output = input.replaceAll("[-+.^:,]",""); output = output.replaceAll("(\\r|\\n)", ""); output = output.toUpperCase(); output = output.replaceAll("[^XYZ]", ""); return output; } When i print my 'input' string of length 97498, it prints successfully. My output string after cleanup is of length 94788. I can print the size using output.length() but when I try to print this in Eclipse, output is empty and i can see in eclipse output console header. Since this is not my final program, so I ignored this and proceeded to next method that does pattern matching on this 'cleaned-up' string. Here is code for pattern matching: public static List<Integer> getIntervals(String input, String regex) { List<Integer> output = new ArrayList<Integer> (); // Do pattern matching Pattern p1 = Pattern.compile(regex); Matcher m1 = p1.matcher(input); // If match found while (m1.find()) { output.add(m1.start()); output.add(m1.end()); } return output; } Based on this program, i identify the start and end intervals of my pattern match as 12351 and 87314. I tried to print this match as output.substring(12351, 87314) and only get blank output. Numerous hit and trial runs resulted in the conclusion that biggest substring that i can print is of length 4679. If i try 4680, i again get blank input. My confusion is that if i was able to print original string (97498) length, why i couldnt print the cleaned-up string (length 94788) or the substring (length 4679). Is it due to regular expression implementation which may be causing some memory issues and my system is not able to handle that? I have 4GB installed memory.

  • Calculation error in Datasheet view in SharePoint

    - by Marius
    I have a custom list, with calculation, in SharePoint. Everything worked fine until recently when the DataSheet will show strange or wrong % calculation in a % column. But the Standard View will show correct values. IT checked the server side and everything looked ok, I checked the formulas and even re-did them in the column and the issue persist. Anyone, any suggestion? Thanks,

  • Standard Interfaces

    - by Amir Rachum
    I've used Java for some time and I keep hearing about interfaces such as Cloneable, Iterable and other X-ables. I was wondering if there is a list somewhere of all of these and more importantly - which ones do you regularly use day-to-day? For example, I've read that Cloneable is considered badly written and isn't widely used.

  • Iterating over consecutive sublists in Python

    - by Anthony Labarre
    Does Python offer a way to iterate over all "consecutive sublists" of a given list L - i.e. sublists of L where any two consecutive elements are also consecutive in L - or should I write my own? (Example: if L = [1, 2, 3], then the set over which I want to iterate is {[1], [2], [3], [1, 2], [2,3], [1, 2, 3]}. [1, 3] is skipped since 1 and 3 are not consecutive in L.)

  • what would be a frozen dict ?

    - by dugres
    A frozen set is a frozenset. A frozen list could be a tuple. What would be a frozen dict ? An immutable, hashable dict. I guess it could be something like collections.namedtuple, but namedtuple is more like a frozenkeys dict (an half-frozen dict). No ?

  • How can one prevent page breaks between Tables in SQL Reporting Services 2005?

    - by James
    I've been developing an SSRS 2005 report (a form letter) that contains two tables. The first "table" uses DataSet "A" to populate address fields on letterhead. The second table uses DataSet "B" to display a basic list of records that pertain to the addressed party. Even though the two tables are within the same page and all PageBreak* properties are set to "False", SSRS renders the report as two pages. How can I force both tables to render in series, without any forced page breaks?

  • how do I get all checkbox variables even if not checked from HTML to PHP?

    - by netrox
    I noticed that PHP seems to return only values of checked checkboxes. I would like to see a list of checkboxes, not just values of checked checkboxes. Is there a way to detect variables of unchecked boxes? I asked because I want to be able to update settings. For example, I have a few options that are already checked but if an user decides to uncheck an option, I need to know that unchecked value so I can update the option to be disabled.

    - by ablmf
    There is a m2m relation in my models, User and Role. I want to merge a role, but i DO NOT want this merge has any effect on user and role relation-ship. Unfortunately, for some complicate reason, role.users if not empty. I tried to set role.users = None, but SA complains None is not a list. At this moment, I use sqlalchemy.orm.attributes.del_attribute, but I don't know if it's provided for this purpose.
