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'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...
