How to create an empty plot using ggplot2 in R?
The two most easy ways to create an empty plot using ggplot2 are using geom_blank function and also adding the theme_bw along with the geom_blank. The geom_blank will create an empty plot with white gridlines and grey background, on the other hand, addition of theme_bw will create the empty plot with grey gridlines and white background.
Example
Consider the below data frame:
> set.seed(151) > x<-rnorm(20) > y<-rnorm(20,1,0.5) > df<-data.frame(x,y) > df
Output
x y 1 -0.05153895 0.3139643 2 0.76573738 0.1816184 3 -0.14673959 0.8201743 4 -0.11318581 1.6005576 5 -0.39551140 0.6770630 6 0.78227595 0.7446956 7 -1.39747811 0.7004385 8 -1.01883832 1.2728014 9 0.22947586 0.7543531 10 0.67217297 1.0957678 11 -0.48455178 0.7207362 12 0.56060896 1.4613498 13 0.06615648 1.5769990 14 -1.34987612 0.3137949 15 -0.24291581 1.6450906 16 -1.23674102 1.5774510 17 -1.47467765 1.7228397 18 2.43715892 1.1305064 19 0.67352581 1.9645730 20 0.31003951 0.7000570
Loading ggplot2 package and creating an empty plot with grey background:
Example
> library(ggplot2) > ggplot(df,aes(x,y))+geom_blank()
Output:
Creating an empty plot with white background:
Example
> ggplot(df,aes(x,y))+geom_blank()+theme_bw()
Output:
