Agregar barras de error a una tabla de barras con múltiples grupos

Question

Tengo la siguiente tabla de barras a la que quiero agregar barras de error.

library(lattice)  
barchart(Change~fTreat,groups=Process,change, 
      auto.key=list(points=FALSE,rectangles=TRUE), 
      panel=function(x, y,...){ 
      panel.barchart(x,y,origin = 0,...); 
      panel.abline(h=0,col="black",...); 
      } 
     ) 

He intentado usar los panel.errbars del paquete memisc la que funciona muy bien para xyplots, pero cuando lo añado a mi código no respeta los grupos.

library(memisc)  
barchart(cbind(Change,lower,upper)~fTreat,groups=Process,change, 
    ylab="Pocertage change", 
    ylim=-115:50, 
    scales=list(alternating=FALSE, 
       tick.number=7, 
       tck=c(-1,0)), 
    panel=function(x, y,groups,...){ 
     panel.barchart(x,y=change$Change,groups=change$Process,origin = 0,...); 
     panel.abline(h=0,col="black",...); 
     panel.errbars(x,y,make.grid="none",ewidth=0.2,type="n",...) 
    } 
    ) 

¿Alguna idea de cómo agregar barras de error a mi terreno, ya sea usando los panel.errbars o cualquier otra función?

Los datos:

structure(list(Treat = structure(c(3L, 4L, 1L, 2L, 3L, 4L, 1L, 
2L), .Label = c("12-380", "12-750", "8-380", "8-750"), class = "factor"), 
    Process = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L), .Label = c("Resp", 
    "Cal"), class = c("ordered", "factor")), Change = c(-33.05, 
    -34.74, 20.94, 18.06, 6.85, -28.57, -8.1, -78.72), upper = c(-13.22896628, 
    -28.61149669, 31.29930461, 27.30173776, 39.73271282, 9.458372948, 
    13.11035572, -47.03745704), lower = c(-52.86120694, -40.87446411, 
    10.57421563, 8.822042178, -26.03144161, -66.60447035, -29.30563327, 
    -110.3973761), fTreat = structure(c(1L, 2L, 3L, 4L, 1L, 2L, 
    3L, 4L), .Label = c("8-380", "8-750", "12-380", "12-750"), class = c("ordered", 
    "factor"))), .Names = c("Treat", "Process", "Change", "upper", 
"lower", "fTreat"), row.names = c(NA, -8L), class = "data.frame")

Aquí es otra una Swer me dieron usando celosía.

prepanel=function(y, stderr, subscripts=subscripts, ...){ 
    uy <- as.numeric(y+stderr[subscripts]) 
    ly <- as.numeric(y-stderr[subscripts]) 
    list(ylim=range(y,uy,ly, finite=TRUE)) 
} 
panel.err=function(x, y, subscripts, groups, stderr, box.ratio, ...){ 
    d <- 1/(nlevels(groups)+nlevels(groups)/box.ratio) 
    g <- (as.numeric(groups[subscripts])-1); g <- (g-median(g))*d 
    panel.arrows(as.numeric(x)+g,y-stderr[subscripts], as.numeric(x)+g, y+stderr[subscripts], 
       code=3,angle=90, length=0.025) 
} 
barchart(Change~fTreat,groups=Process,change, 
     stderr=change$stderr, 
     ylab="Pocertage change", 
     xlab="Treatment", 
     ylim=-115:50, 
     auto.key=list(points=FALSE,rectangles=TRUE,columns=2), 
     scales=list(alternating=FALSE, 
        tick.number=7, 
        tck=c(-1,0)), 
     prepanel=prepanel, 
     panel=function(x, y, subscripts, groups, stderr, box.ratio, ...){ 
      panel.barchart(x, y, subscripts=subscripts, 
          groups=groups, box.ratio=box.ratio,origin=0, ...) 
      panel.abline(h=0,col="black",...) 
      panel.err(x, y, subscripts=subscripts, 
         groups=groups, box.ratio=box.ratio,stderr=change$stderr) 
      } 
     )

Estos son los datos modificados:

change <- structure(list(Treat = structure(c(3L, 4L, 1L, 2L, 3L, 4L, 1L, 
2L), .Label = c("12-380", "12-750", "8-380", "8-750"), class = "factor"), 
    Process = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L), .Label = c("Respiration", 
    "Calcification"), class = c("ordered", "factor")), Change = c(-33L, 
    -35L, 21L, 18L, 7L, -29L, -8L, -79L), stderr = c(20L, 6L, 
    10L, 9L, 33L, 38L, 21L, 32L), fTreat = structure(c(1L, 2L, 
    3L, 4L, 1L, 2L, 3L, 4L), .Label = c("8-380", "8-750", "12-380",

), class = "data.frame")

Esto no es lo que estás pidiendo, pero la trama es bastante fácil de hacer con ggplot2 (en un caso que se trata de una opción)

dt <- structure(list(Treat = structure(c(3L, 4L, 1L, 2L, 3L, 4L, 1L, 
2L), .Label = c("12-380", "12-750", "8-380", "8-750"), class = "factor"), 
    Process = structure(c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L), .Label = c("Resp", 
    "Cal"), class = c("ordered", "factor")), Change = c(-33.05, 
    -34.74, 20.94, 18.06, 6.85, -28.57, -8.1, -78.72), upper = c(-13.22896628, 
    -28.61149669, 31.29930461, 27.30173776, 39.73271282, 9.458372948, 
    13.11035572, -47.03745704), lower = c(-52.86120694, -40.87446411, 
    10.57421563, 8.822042178, -26.03144161, -66.60447035, -29.30563327, 
    -110.3973761), fTreat = structure(c(1L, 2L, 3L, 4L, 1L, 2L, 
    3L, 4L), .Label = c("8-380", "8-750", "12-380", "12-750"), class = c("ordered", 
    "factor"))), .Names = c("Treat", "Process", "Change", "upper", 
"lower", "fTreat"), row.names = c(NA, -8L), class = "data.frame") 

a <- ggplot(dt, aes(y = Change, x = Treat, ymax = upper, ymin = lower)) 
dodge <- position_dodge(width=0.9) 
a + geom_bar(aes(fill = Process), position = dodge) + 
geom_errorbar(aes(fill = Process), position = dodge, width = 0.2)
