如何在格子圖形中設置條形標籤字體大小R

Question

我已經創建了三個面板的格子圖。我可以控制軸和刻度標籤的字體大小，但我一直無法弄清楚如何增加條形標籤的字體大小。下面是一個具體的例子：

# See below for the fake data to run this code 
library(lattice) 
barchart(choice ~ yes+no+not.app|group, data=data, 
     stack=TRUE, col=c("green","red","blue"), 
     xlim=c(0,100), layout=c(3,1), 
     scales=list(cex=c(1.4,1.4), alternating=3), 
     xlab=list(label="Percent of Respondents", fontsize=20), 
     main="") 

下面是這段代碼產生的圖。請注意，除條形標籤（「組1」，「組2」，「組3」）之外，所有字體都很好看。我一直在圍繞R-help和Stack Overflow進行釣魚，但一直未能完成這項工作。有誰知道魔法咒語？

data = structure(list(choice = c("Choice 1", "Choice 1", "Choice 1", 
"Choice 2", "Choice 2", "Choice 2", "Choice 3", "Choice 3", "Choice 3", 
"Choice 4", "Choice 4", "Choice 4"), group = c("Group 1", "Group 2", 
"Group 3", "Group 1", "Group 2", "Group 3", "Group 1", "Group 2", 
"Group 3", "Group 1", "Group 2", "Group 3"), yes = c(23.53, 20.47, 
22.94, 16.51, 16.54, 16.51, 9.68, 13.39, 10.4, 24.48, 29.92, 
25.54), no = c(41.37, 37.01, 40.52, 48.39, 40.94, 46.94, 55.22, 
44.09, 53.06, 40.42, 27.56, 37.92), not.app = c(35.1, 42.52, 
36.54, 35.1, 42.52, 36.54, 35.1, 42.52, 36.54, 35.1, 42.52, 36.54 
)), .Names = c("choice", "group", "yes", "no", "not.app"), row.names = c(NA, 
12L), class = "data.frame")

嘗試（於提供一個例子良好的工作）這樣的：

barchart(choice ~ yes+no+not.app|group, data=data, 
    par.strip.text=list(cex=2), 
    stack=TRUE, col=c("green","red","blue"), 
    xlim=c(0,100), layout=c(3,1), 
    scales=list(cex=c(1.4,1.4), alternating=3), 
    xlab=list(label="Percent of Respondents", fontsize=20), 
    main="") 

要了解更多關於如何管理上，有類型：?strip.default還有其他槓桿來扔在strip.custom。另請參閱latticeExtra軟件包，該軟件包可以用useOuterStrips將條帶放在兩側。
