r - 如何在plotly的更新版本中设置布局？

Question

我正在尝试使用新版本的 plotly 绘制一个简单的图形，但我不断收到以下错误

Error in UseMethod("layout") : no applicable method for 'layout' applied to an object of class "character"

这是我的代码的样子:

library(plotly)
library(RColorBrewer)

year <- c(1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006)
amt <- c(11, 16, 21, 27, 33, 37, 43, 54, 68, 94, 128, 170, 213, 258, 307, 348, 385)

data <- data.frame(year, amt)

data$year <- factor(data$year, levels = data[["year"]])

xaxis <- list(title = "Years",
          showline = TRUE,
          showgrid = FALSE,
          showticklabels = TRUE,
          linecolor = 'black',
          linewidth = 1,
          autotick = FALSE,
          ticks = 'outside',
          tickcolor = 'black',
          tickwidth = 2,
          ticklen = 5,
          tickfont = list(family = 'Cambria',
                          size = 10,
                          color = 'rgb(82, 82, 82)'))

yaxis <- list(title = "Years",
          showline = TRUE,
          showgrid = FALSE,
          showticklabels = TRUE,
          linecolor = 'black',
          linewidth = 1,
          autotick = FALSE,
          ticks = 'outside',
          tickcolor = 'black',
          tickwidth = 2,
          ticklen = 5,
          tickfont = list(family = 'Cambria',
                          size = 10,
                          color = 'rgb(82, 82, 82)'))


plot_ly(data, x = ~year,
    y = ~amt,
    name= '',
    type='scatter',
    mode = 'lines+markers',
    line = list(color = toRGB('#964f4d')),
    marker = list(color = toRGB("#964f4d")))

layout(title = 'Pre-purchase financing poll',
   xaxis = layout.xaxis,
   yaxis = layout.yaxis)

布局命令不起作用，如果有人知道为什么以及我该怎么做，我将不胜感激!

谢谢!

您可以尝试添加 %>%之间plot_ly和 layout .
