R画图并保存（pdf/jpg/png等）

• 以PDF为例

library(ggplot2)

# Opening the graphical device
# Customizing the output
pdf("p1umap.pdf",         # File name
    width = 8, height = 7, # Width and height in inches
    bg = "transparent",          # Background color
    colormodel = "cmyk"    # Color model (cmyk is required for most publications)
    paper = "A4")          # Paper size

# Creating a plot
p1 <- DimPlot(w15_1_2_st.obj.rds, reduction = "umap")

# Closing the graphical device
dev.off()

svg/png/jpg以此类推，改名称即可
