i'd interpolate on many individual data.frames stored within list using akima package. having split original data frame: store <- split(data, data$frameid) i tried this... results <- lapply(store, interp, x = lon, y = lat, z = precip) but error message error in interp(x = lon, y = lat, z = precip) : object 'lat' not found . single results can successfully generated following.. results <-list() # create , empty list results results[[i]]<-with(store$`600`, interp(x = lon, y = lat, z = precip)). where 600 represents name of 1 of data.frames within list. however attempting generalise entire list using loop-approach.. i=1 (i in i:length(store)){ results[[i]]<-with(store$`i`, interp(x = lon, y = lat, z = precip)) } i again receive error in interp(x = lon, y = lat, z = precip) : object 'lat' not found . any advice appreciated. using suggestions, , accounting duplicate points (same lat , lon stations) job. i=...

i have array of object obj.arr in javascript. assigned new object. var obj_arr_new = obj.arr; the problem when modify obj_arr_new , obj.arr gets modified well. not want that. how can make obj_arr_new copy of obj.arr , when modify obj_arr_new , obj.arr untouched? i using node.js v6. open using node.js module. told me lodash can job. answer using lodash helpful. lodash indeed has _.clonedeep(value) purpose. var obj_arr_new = _.clonedeep(obj.arr); it recursively clone "arrays, array buffers, booleans, date objects, maps, numbers, object objects, regexes, sets, strings, symbols, , typed arrays" modifying bits of clone doesn't affect original, or vice versa. documentation

a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] if len(set(a)) > len(set(b)): # finds biggest list largest = smallest = b else: largest = b smallest = common = largest in largest: if not in smallest: common.remove(i) print(common) prints: [1, 2, 3, 5, 7, 8, 10, 12, 13] 7, 9, 10, 11, 12 shouldnt in list. because aint in smaller list. what doing wrong? your code relies on assumption statements like largest=a copy list largest. this not true in python. rather statement makes largest reference old list a. your code, copy lists properly, should this: a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13] if len(set(a)) > len(set(b)): # finds biggest list largest = list(a) smallest = list(b) else: largest = list(b) smallest = list(a) common = list(largest) in largest: if not in smallest: common.remove(i) print(com...

i'm testing different compressions spritesheets game on ios. in surprising way, more important memory (ram) use pvr 2 bits alpha instead of png 32 (rgba 4444). consumption 25% higher pvr 2 bits instead of png 32 once spritesheets loaded inside memory. i'm using instruments xcode verify memory use on physical device (ipad air 2) i'm using texturepacker generate spritesheets. i've read evrywhere pvr 2 or 4 less memory consumer png 32. how possible ? edit: this strange because according observations, pvrtc 4 bits rgba uses lot more memory (ram) png 32, neraly 3 times more according instruments xcode. pvrtc 2 bits rgba 25% higher png 32 rgba 4444. i'm talking live ram consomption, not disque size has nothing , not problem. seems ios manages pvr differently it's supposed do, when loading them ram. edit2: my textures 2048x2048, there pot , have square format. evrything work fine, except ram consomption higher should be. make tests physical ipad air 2 d...
