Making SPI plots

[Lfssekyondwa]

Hey,
I am trying to plot SPI but wherever I type the function <plot.spei(sp13)> the following error comes up.
Any help?

you seem to have shared a transparent image.
errors are typically text, and this forum is text, so its a good match. share your error to us as text?
also what are you doing that would involve angle brackets ? < and >
seems like you might be doing xml, or html, rather than R ?

I type the function plot.spei(sp13)

And the error is, could not find function "plot.spei"

[nirgrahamuk]

where would plot.spei come from ?
you likely forgot a library() call

I am new to this software please. I was following a tutorial from youtube. The person did those steps and his plot came out.

Could you please give me the necessary codes and packages I need to generate SPI plots?

Thank you so much

@nirgrahamuk

plot.spei

i typed this into google for you..
it told me SPEI
so you should do

install.packages(`SPEI`) 

run that, but dont include it in your script because you wont need it again, or at least, comment it out.

then the script can have

library(SPEI)

at the top of it.
