Please see the code below, is not allowing me to save the plot as an object to later add multiple plots in one figure and neither add the title using the function "main". Any help would be appreciated

plot.new()

draw version pie chart first

version_chart <-
floating.pie(
xpos = center_x,
ypos = center_y,
x = version_data$Aromatic3,
radius = 0.35,
border = "white",
col = version_colors,
)

add labels for version pie chart

pie.labels(
x = center_x,
y = center_y,
angles = version_chart,
labels = version_labels,
radius = 0.38,
bg = NULL,
cex = 0.8,
font = 2,
col = "gray40"
)

overlay browser pie chart

browser_chart <-
floating.pie(
xpos = center_x,
ypos = center_y,
x = browser_data$x,
radius = 0.25,
border = "white",
col = browser_colors
)

add labels for browser pie chart

pie.labels(
x = center_x,
y = center_y,
angles = browser_chart,
labels = browser_data$var_aromatic,
radius = 0.125,
bg = NULL,
cex = 0.8,
font = 2,
col = "white"
)
