this scalaz tutorial provides example of using filterm method, not explain it. list(1, 2, 3) filterm { x => list(true, false) } res19: list[list[int]] = list(list(1, 2, 3), list(1, 2), list(1, 3), list(1), list(2, 3), list(2), list(3), list()) i see can pass boolean list of size. filterm method? also, there book/tutorial of scalaz bit more explanations? this pretty old question. i'll answer in case else wondering. you can find pretty explanation learn haskell good! . search filterm in link referenced. in book, says following (you can kind of make out haskell syntax): the filter function pretty bread of haskell programming (map being butter). takes predicate , list filter out , returns new list elements satisfy predicate kept. type this: filter :: (a -> bool) -> [a] -> [a] the predicate takes element of list , returns bool value. now, if bool value returned monadic value? whoa! is, if came context? work? instance, if every true o

i have bulk views create entire database. to create view general syntax follows: create view [table_name] select [column1], [column2], [column3], [column4] [table_name] check option; i set column names in script above querying column names ( [colulmn1] , [column2] , etc) information_schema.columns . is there way achieve table name? coalesce friend programmer. want csv list of columns. using dynamic sql can auto generate rest of code. declare @columns varchar(max) select @columns = null select @columns = coalesce(@columns+',','')+c.name syscolumns c inner join sysobjects o on c.id = o.id o.name = 'change me table name' select @columns select ' create view ' + 'cool view name' + ' ' + ' select ' + @columns + ' '+ ' change me table name '+ ' check option;' edit i purposely didn't declare view anywhere. if want declare view execute scripts so. but should n

i've got these template tags @register.assignment_tag def test1(): return 2 @register.simple_tag def test2(): return 2 in template i've got this {% test1 test1_var %} {% if test1_var > 0 %}test1{% endif %} {% if test2 > 0 %}test2{% endif %} results in test1 what want template tag appears if greater 0, cannot believe assignment_tag right solution that. why test2 not work? the test2 inside if statement not call template tag; can refer (non-existent) context variable. that's why assignment tag works, because set such variable. if don't assignment tag, might consider doing whole comparison inside tag, outputs test1/test2 value directly.

this question has answer here: dynamically select data frame columns using $ , vector of column names 4 answers i want create function count values in variable in subsetted dataset, function not working supposed to. selected_cyl_6 <- subset(mtcars, mtcars$cyl==6) selected_cyl_4 <- subset(mtcars, mtcars$cyl==4) count <- function(group,variable) { sum(group$variable == 4) } count(selected_cyl_6,gear) # [1] 0 the answer should 4. however, if use sum directly correct answer sum(selected_cyl_6$gear==4) # [1] 4 another example count(selected_cyl_4,gear) # [1] 0 sum(selected_cyl_4$gear==4) # [1] 8 what doing wrong? it's using dollar sign shortcut in function. see fortunes::fortune(343) . some options, using bracket notation. first, standard evaluation give variable name in quotes when use function. count <- function(group, va

i met strange behavior when using add_property of boost.python. here example codes, add 2 properties (read-only & read-write) wrapped class. #include <boost/python.hpp> using namespace boost::python; struct x { x( int value ) : val( value ) {} int get_value() const { return val; } void set_value(int value) { val = value; } int val; }; boost_python_module(hello) { class_<x>("x", init<int>() ) // note order .add_property( "val_r", &x::get_value ) // read-only first .add_property( "val_rw", &x::get_value, &x::set_value ) // read-write second ; } and build command: $ g++ -i/usr/include/python2.7 -shared -l/usr/local/lib -o bp.dll bp.cpp -lboost_python -lpython2.7 i'm working in cygwin x86_64, file extension .dll . ubuntu change output extension .so . when importing bp module, crashes segmentation fault . core dump file doesn't contain call

i have data set different categories. let's a,b,c , d. here how data set looks like v1 v2 v3 1 na 1 0.1 2 2 2 0.2 3 3 na 0.1 4 4 4 0.3 5 na na 0.4 6 na na 0.8 7 7 7 0.2 8 na 8 0.1 9 9 na 0.6 10 na na 0.1 the lines that: v1 column not na in category a v2 column not na in category b (v1 column not na or v2 column not na )are in category c all line in dataframe in category d in case of example above: there lines fall , c @ same time(like line 3). line 1 in category b , c. therefore, number of category c may less number of a+b. 10 lines in category d. i want use ggplot2 plot violin plot of category a,b,c , d according values in v3. (that b c d in x-axis , v3 in y-axis) does got hint? tried ggplot2 seems can't not deal overlapped categories. if data have column specified categories, work fine: v1 v2 v3 group 1 na
