如果我编织文档，则会在RStudio：“查看PDF”窗口中获得pdf输出，该窗口通常会在命令中弹出或刷新。

例如，此查看器是否可以位于RStudio的右下窗格中？

我正在重新提出这个问题: 如何在R Markdown的情节中包装文字？:

'目前R中R Markdown的默认值是让一行文字与情节一致,但这看起来很尴尬,我想通过让文字环绕绘图来节省空间(图左对齐,文字环绕)正确的).'

df <- structure(list(Cars = structure(3:1, .Label = c("Ford ", "Mazda", "Merc"), class = "factor"), Model = structure(c(2L, 1L, 3L), .Label = c("c", "e-class", "gt"), class = "factor"), Color = structure(1:3, .Label = c("Black ", "Blue", "Red"), class = "factor")), class = "data.frame", row.names = c(NA, -3L))
argument <- structure(list(NewVar = structure(3:2, .Label = c("", "SKU", "Vehicle"), class = "factor"), Input = structure(2:3, .Label = c("", "Cars", "Model"), class = "factor")), row.names = 1:2, class = "data.frame")
after <- structure(list(Cars = …

df$X <- gsub("[+]", "(+)", df$X)
df$X<- gsub("[-]", "(-)", df$X)

这两个命令替换了我的列中的所有+和 - 和(+)( - ),即使我只想在启动单元格时进行更改.
