如何在Wordcloud R中增加绘制区域的大小（边界，因为某些单词被切掉）

Question

我使用Shiny仪表板，并且输出是在dashboardBody（框中，（输出

    dashboardPage(skin = "blue",
      dashboardHeader(title = "Word Cloud",titleWidth = 320),
      dashboardSidebar(tags$style(HTML(".main-sidebar{width: 320px;}")),
        sidebarMenu(
          menuItem("Type",startExpanded = TRUE,
                   selectInput("selection", "Please, Choose Type:",
                               choices = books),
                   actionButton("update", "Change"),
                   hr()

          ),
          menuItem("Frequency",startExpanded = TRUE,
                   sliderInput("freq",
                               "Please, choose Frequency:",
                               min = 100,  max = 1000, value = 20,step=50)

          ),
