r - Remove extra space beyond xlim and ylim -


i'd make density plot axes right next (or @ least close to) tick marks. seen in mwe, ggplot2 reserved space between tick marks , axes in both x- , y-axis, when have specified xlim , ylim. how can remove them?

with other kinds of plots, seems can call scale_y_continuous(limits=c(0, 100), expand = c(0, 0)) (for example), calling scale_linetype_manual() these parameters doesn't seem anything.

also note in note here drawing axes using geom_segment. there better way this?

set.seed(0) the.df <- data.frame( x = rnorm(800, 50, 10), group = rep(letters[1:8], each = 100))  p <- ggplot(the.df) +      stat_density(aes(x = x, linetype = group), geom = "line", position = "identity") +     xlim(10, 90) + ylim(0, 0.06) +     scale_linetype_manual(values = c("11", "12", "13", "14", "21", "22", "23", "24")) +     geom_segment(aes(x = 10, y = 0, xend = 90, yend = 0)) +     geom_segment(aes(x = 10, y = 0, xend = 10, yend = 0.06))  p

turns out scale_x_continuous() , scale_x_continuous work. didn't use them correctly earlier.

set.seed(0) the.df <- data.frame( x = rnorm(800, 50, 10), group = rep(letters[1:8], each = 100))  p <- ggplot(the.df) +      stat_density(aes(x = x, linetype = group), geom = "line", position = "identity") +     scale_linetype_manual(values = c("11", "12", "13", "14", "21", "22", "23", "24")) +     scale_x_continuous(limits=c(10, 90), expand = c(0, 0)) +     scale_y_continuous(limits=c(0, 0.06), expand = c(0, 0)) +     geom_segment(aes(x = 10, y = 0, xend = 90, yend = 0)) +     geom_segment(aes(x = 10, y = 0, xend = 10, yend = 0.06))  p

how to proxy from https to http with lighttpd -

i have internal site (192.168.2.1) accessible http on different server run public web-server using lighttpd. can make internal site accessible outside work follows $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "192.168.2.1", "port" => 8000 ) ) } this works, use https outside world. question is, how can proxy going https http ? i've tried this: $server["socket"] == ":443" { $http["host"] == "internal.example.com" { ... proxy.server = ( "" => ( "internal" => ( "host" => "http://192.168.2.1", "port" => 8000 ) ) } } but doesn't seem wor...

android - Automated my builds -

i have multiple app , android project want automated in build , release sequence. have ant script build , create apk of app. want have 1 script or ant file start build sequence app. maybe don't konw search, can't find easy documentation on ant. the point of use jenkins ant (or maven, i'm not sure of difference between them now) automated build sequence when people commit on project. any int appreciated maven dependencies (over ant) don't need pass around jars. recommend maven on ant day. syntax , overall process easier understand, @ end of both build tools. if able to, more recommend upgrading gradle. easy create different build types , create them ./gradlew assemble here project jake wharton can see power of gradle. there release , debug build, can make lot more if like. https://github.com/jakewharton/u2020 here android docs gradle http://tools.android.com/tech-docs/new-build-system/user-guide . if can't find looking here, check out main grad...
