添加Openair windRose绘图面板之间的间距

Question

我使用openair包创建了一些windrose图，我对它们的效果非常满意，但从美学上讲，在面板之间留出一些空间会很好。下面是一个例子：

# windrose plot----
library(openair)
data("mydata")

windRose(mydata[1:144,], ws="ws", wd="wd", 
         paddle = F, 
         type = 'weekday', 
         key.header = 'Wind Speed (m/s)',
         key.footer = "",
         annotate = F,
         angle = 30, # angle of "spokes"...sort of bins for wind direction
         cols =  'jet',
         key.position = 'right',
         dig.lab = 2,
         statistic = 'prop.count', #“prop.count” sizes bins according to the 
         # proportion of the frequency of measurements
         fontsize = 20,
         grid.line = 100,
         max.freq = 105, # maximum value for the radial limits
         key = list(header = "Wind Speed (m/s)",
                    footer = '',
                    labels = c('0 to 2', '2 to 4', 
                               '4 to 6','6 or more'),
                    breaks = c(0,2,4,6)),
         layout = c(6,1)
)

有没有人知道如何在面板之间增加空间？

Answer 1

经过深入研究，我发现这个绘图函数利用了网格绘图，下面是对它们的一个很好的概述：https://www.stat.auckland.ac.nz/~ihaka/787/lectures-trellis.pdf

具体地说，xyplot函数用于创建网格图。?xyplot的帮助文档显示，您可以调整参数between以实现面板之间的间距。between参数是一个列表，其中包含表示面板之间间距的x和y值。因此，我们可以简单地通过添加参数between = list(x=0.25, y = 0.25)来调整上面的代码，并可以根据自己的喜好调整x和y，如下所示：

library(openair)
data("mydata")

windRose(mydata[1:144,], ws="ws", wd="wd", 
         paddle = F, 
         type = 'weekday', 
         key.header = 'Wind Speed (m/s)',
         key.footer = "",
         annotate = F,
         angle = 30, # angle of "spokes"...sort of bins for wind direction
         cols =  'jet',
         key.position = 'right',
         dig.lab = 2,
         statistic = 'prop.count', #“prop.count” sizes bins according to the 
         # proportion of the frequency of measurements
         fontsize = 20,
         grid.line = 100,
         max.freq = 105, # maximum value for the radial limits
         key = list(header = "Wind Speed (m/s)",
                    footer = '',
                    labels = c('0 to 2', '2 to 4', 
                               '4 to 6','6 or more'),
                    breaks = c(0,2,4,6)),
         layout = c(6,1),
         between = list(x=0.25, y=0.25)
)
