[R] Creating hanging bar plot in r from dplyr

[Jeff Newmiller]

Not really sure I understand what you want. Here is some code to 
consider:

################

library(ggplot2)
library(dplyr)
library(tidyr)

dta <- read.table( text =
"samp.N   RSQ    MRB_uc  MRB_sb  MRB_bp
  50      0.3      1.42    37.6   37.6
  50      0.4      8.61    43.1   43.1
  50      0.5      7.41    31.6   31.6
  50      0.6      5.06    21.5   21.5
  50      0.7      3.38    14.1   14.1
  50      0.8     -1.07    5.16   5.16
100      0.3     -6.41    40.3   40.3
100      0.4     -10.6    21.0   21.0
100      0.5     -9.02    13.2   13.2
100      0.6     -9.85    5.14   5.14
100      0.7     -7.94    2.08   2.08
100      0.8     -4.81    1.28   1.28
", header = TRUE )
dta2 <- (   dta
         %>% mutate( samp.N = factor( samp.N )
                   , RSQ = factor( RSQ )
                   )
         %>% gather( Measure, value, -c( samp.N, RSQ ) )
         )

ggplot( dta2, aes( x = RSQ, y = value, fill = samp.N ) ) +
   geom_bar( stat = "identity", position = "dodge", colour = "black" ) +
   facet_wrap( ~ Measure, ncol = 1, scale = "free_y" ) +
   ylab( "" )

> What I want to do is create a hanging bar plot with the x-axis being samp.N value by RSQ value. The bars are then values of MRB_uc, MRB_sb, and MRB_bp. Given some values are negative, some bars will be above zero and others below (hence the hanging bar plot)
