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...
