Plot multiple plots from dataframes stored in list

Question

I am trying to plot multiple plots from each data stored in the list.My code works when I am trying to plot for a single dataframe in a list:

ggplot(data.frame(s[1]), aes(x = No, y = Val))  +
  geom_line(linetype = "dashed",color="red")+geom_point()

but unable to work it when I am running a loop.

for (i in 1:3)
{
  ggplot(data.frame(s[i]), aes(x = No, y = Val))  +
    geom_line(linetype = "dashed",color="red")+geom_point()
  i = i+1
}

How to resolve the issue?

Could you expand on how it doesn't work? Do the plots not show? Do the data look wrong? Would you like to save the plots in a list? Do you get errors? — teunbrand

You can save the plot within the for loop on a variable and print as follows:

for (i in 1:3)
{
  myplot <- ggplot(data.frame(s[i]), aes(x = No, y = Val))  +
    geom_line(linetype = "dashed",color="red")+geom_point()
  print(myplot)

}

You could also store all plots in a list

myplot <- list()
for (i in 1:3) {
   myplot[i] <- ggplot(data.frame(s[i]), aes(x = No, y = Val)) +
   geom_line(linetype = "dashed", color = "red") + 
   geom_point()
}
