Question: While plotting in R in QGIS, only the latest plot appears in 'Result viewer'. What do I do to get all the plots done during script running? Here's the code:

```
##showplots

bin_arr <- c("C:/Users/Madhur/Desktop/Screenshot_1.png", "C:/Users/Madhur/Desktop/Screenshot_2.png")

shp_arr <- c("C:/Users/Madhur/Desktop/SAR_Calibration/Screenshots_SAR/final.png", "C:/Users/Madhur/Desktop/SAR_Calibration/Screenshots_SAR/Screenshot_2.png")

library(imager)

im1<-load.image(bin_arr[2])
plot(im1)

im2<-load.image(shp_arr[1])
plot(im2)

im<-load.image(shp_arr[2])
plot(im)

```

I only get the plot corresponding to the last plot statement i.e. `plot(im)`. I don't know if this is related or not but I ran the same script on `cmd` using `Rscript script-name.R` and not a single plot appeared. 
Please help me show multiple plots in QGIS.

Answer: 
To create a new window for each plot, use the windows() command. Editing your code to the following should create each plot without overwriting the previous results: 

```
##showplots

bin_arr <- c("C:/Users/Madhur/Desktop/Screenshot_1.png", "C:/Users/Madhur/Desktop/Screenshot_2.png")

shp_arr <- c("C:/Users/Madhur/Desktop/SAR_Calibration/Screenshots_SAR/final.png", "C:/Users/Madhur/Desktop/SAR_Calibration/Screenshots_SAR/Screenshot_2.png")

library(imager)

im1<-load.image(bin_arr[2])
windows(); plot(im1)

im2<-load.image(shp_arr[1])
windows(); plot(im2)

im<-load.image(shp_arr[2])
windows(); plot(im)

```
In fact, I cannot display many graphics. Only the last one, as you say.
I arranged a way to store my graphics in files, then I am able to see all of them.

My code is very different than yours, but you will be able to find out.

```
##showplots
require(ggplot2)  
Size = 10
x = 1:Size
y1 = x^2
y2 = x^3

>print('Graphcis are in this directory')
>getwd()

png('y1-plot.png', 800,800)
plot(x,y1)
dev.off()

png('y2-plot.png', 800,800)
plot(x,y2)
dev.off()

ggplot(data.frame(x,y1))+
  aes(x=x, y=y1) +
  geom_line()
ggsave('y1-ggplot.png')

ggplot(data.frame(x,y2))+
  aes(x=x, y=y2) +
  geom_line()
ggsave('y2-ggplot.png')

```

In my directory, I can see four graphics.
