i created timer, , wondering if @ possible make timer go slower when reaches second: 1..2..3..4..4.1..4.2 . for example, timer increasing 1 second, @ 4 seconds, time slows down showing milliseconds. if(i = 4) { } it depends on want. of course, can't slow down time, can simulate it. example, check how time has passed. if 1, 2, 3 seconds, nslog 1, 2, 3. when 4 seconds has passed, start logging milliseconds. e.g. if (i < 4) { nslog(@"%d", i); } else { nslog(@"4.%d", - 4); } sure, logging can substituted whatever need. p.s. answer in objective-c, changes nothing.

in following example function returns theme, altered extend (in minimum example extreme ugly modifications...). adding function first time ggplot not anything, adding further plot works intenden. how can make sure, function works alreay in first application, or error in thinking? require(ggplot2) # minimal example: function returning theme modifications mytheme <- function(size = 3) { th.my <- theme_set(theme_bw(base_size=size)) th.my$axis.ticks$size = 1 return (th.my) } # plot something, applying theme function first time fig1 <- ggplot(data = mtcars, aes(x = mpg)) + geom_point(aes(y = hp)) + mytheme() print(fig1) # same, again fig2 <- ggplot(data = mtcars, aes(x = mpg)) + geom_point(aes(y = hp)) + mytheme() print(fig2) as 1 can see in following plots, first time theme not applied, second time worked... this because theme_set changes default future calls ggplot , not change "current" theme. if create o
