Dot plot

import library

creating a function for dot plots which takes dataset iris ,a continous variable and group variable as its arguments

plot_dot_plots <- function(data,continuous_var,group_var)
{
  library(reshape2)
  meltdata<-melt(data,id.vars=group_var,measures_vars=continuous_var)
  ggplot(meltdata,aes_string(x="variable",y="value",color =group_var))+
    geom_point(position=position_dodge(width =0.5))+
    labs(title="dot plot of variables grouped by categories",
         x="variables",
         y="values"
    )+
    theme_minimal()
}

concat 2 groups sepal length and width as continous variable and call the functioin by passing iris as dataset
