轉軸和斜體書寫

Question

我想中的R以適應情節，和我有一些掙扎旋轉x軸標籤，我已經嘗試過這個命令：

標籤= lablist，SRT = 45， pos = 1，xpd = TRUE

但它不工作，因爲它說它不知道標籤。此外，我不知道如何獲得斜體標籤名稱。

有沒有人有任何建議？謝謝:)

Answer 1

從?par：（不是你想要的）

'srt' The string rotation in degrees. See the comment about 
    'crt'. Only supported by 'text'. 

與'las'和'font'繼續：

'las' numeric in {0,1,2,3}; the style of axis labels. 
     0: always parallel to the axis [_default_], 
     1: always horizontal, 
     2: always perpendicular to the axis, 
     3: always vertical. 
'font' An integer which specifies which font to use for text. If 
     possible, device drivers arrange so that 1 corresponds to 
     plain text (the default), 2 to bold face, 3 to italic and 4 
     to bold italic. 

這些可以給你：

barplot(setNames(100 * 1:3, nm=c("abc","def","ghi")), las=2, font=3) 

或許：

barplot(setNames(100 * 1:3, nm=c("abc","def","ghi")), las=1, font=3)
