visualization - plotting different columns in r -

-

data = 110 columns( x1: x100) (numeric)

i trying plot columns using following code,

      x2=melt(x1)       ggplot(x2,aes(x = value)) +        facet_wrap(~variable,scales = "free_x") +        geom_histogram(aes=(density))       +title(sub = s, line = 5.5)        s<-summary(x1)

i'm want append summary data every column in plot analysis . there alternate this?

thanks.

to knowledge, cannot add subtitles subplots of facet_wrap. change title accomodate want though. here example min, max, mean , median :

data = data.frame(x1=rnorm(100),                   x2=rnorm(100),                   x3=rnorm(100),                   x4=rnorm(100),                   x5=rnorm(100),                   x6=rnorm(100))   library(dplyr) library(tidyr) library(ggplot2)  x <- data %>%    gather(variable,value) %>%   group_by(variable) %>%   mutate(mean=mean(value),             median=median(value),             min=min(value),             max=max(value),             lab=paste(first(variable),"\nmin:",round(min,2),"mean:",round(mean,2),"median:",round(median,2),"max:",round(max,2)))  ggplot(x,aes(x = value)) +    facet_wrap(~lab,scales = "free_x") +    geom_histogram(aes=(density)) +   geom_vline(aes(x=mean))

i've created components , helper methods using c++ , qt used in qml gui. of methods calculate gui elements (size, transformations, scene graph items creation). target arm 32 bit using opengl / eglfs render output. opengl using float , qml using real (defined double ). what should use in c++ do not lose precision? if use qreal ( double ) shouldn't lose precision. if git grep float in qtbase.git , can find out bit more: dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0-* important behavior changes * dist/changes-5.2.0-**************************************************************************** dist/changes-5.2.0- dist/changes-5.2.0- - qt compiled qreal typedef'ed double on dist/changes-5.2.0: platforms. qreal float on arm chipsets before. guarantees more dist/changes-5.2.0- consistent behavior between platforms qt supports, binary dist/chan...
