i create table counter column in cassandra, : create table test_count( pk int, count counter, primary key (pk) ); and after update record like: update test_count set count = count + 1 pk = 1; then want reset count 0, there's no reset command in cql, delete record: delete test_count pk = 1; and re-execute update cql, when select * test_count , there's no record pk = 1 , bug of cassandra? when delete record counter column, disappears forever? how can reset count column 0? how can re-insert record counter column? you can first query counter current value , issue update subtract amount. you can delete counter, , start new counter using different row key. no longer try use original counter. approach might want partition counters day or week, when new day started, you'd start fresh set of zeroed out counters.

i have strange behavior understand. here perl script, check if folders present : #!/usr/bin/env perl use warnings; $root = "c:\\data\\tests"; @check = ("folder1", "folder2", "folder3"); foreach $check (@check){ print $check; print -d "$root\\$check" ?

i'm using spss 20. in dataset list of string variables want recoded numeric. wanted them recoded themselves. realize not possible spss runs through dataset casewise , 1 variable can have 1 type @ time. want them recoded new variables suffix _rec . do repeat var = var_1 var_2 ... var_n. recode var (convert) var_rec. end repeat. but creates 1 new variable var_rec not several new ones. i tried programme workaround: compute job_2 string job(a20) repeat var = var_1 var_2 ... var_n. compute var = job. recode job (convert) job_2. delete variables var. compute var = job_2. end repeat. but doesn't work because delete variables can not used within do repeat loop. so i'm @ original question. you (string variables) can't recoded can using alter type alter type var_1 var_2 var_3 (f8.2). where f8.2 numeric variable of width 8 , 2 decimal points. you can use do repeat multiple stand-in list of variables, following: do repeat old = va...

i'm trying build own print method, based on class "facet". want make specific ggplot when calling print , throws me error message error: ggplot2 doesn't know how deal data of class facetindicator code print.facet <- function(x) { print("hello") # print statement gets outputted fine ggplot(data = x, aes( x = published, y = sma90)) + geom_line() } running ggplot manually same object without class attribute works fine. i've must have missed trivial, can be? you remove facet class when pass object ggplot, or, perhaps more elegantly, via fortify method, fortify.facet <- function(x) {class(x) <- class(x)[-1]; x} print.facet <- function(x) { ggplot(data = x, aes( x = published, y = sma90)) + geom_line() } d <- data.frame(published=1:10, sma90=1:10) class(d) <- c("facet", class(d)) print(d) you consider defining as.data.frame.facet and/or autoplot methods, may feel more natural.
