could not find function "cld"

Hi
This is my first post here, i'm ab it of a newbie on R.

I am running an two way anova based on this script : [https://rstatisticsandresearch.weebly.com/two-way-anova.html](link to script1)

I have had quite some help finding my errors in other topic around here but now that i approach the end of the script there appears a final error.

> cld(posthoc, 
+     alpha=.05,  
+     Letters=letters)
Error in cld(posthoc, alpha = 0.05, Letters = letters) : 
  could not find function "cld"

I guess cld must be in some library ???

if you are going through the script R script part 1 - twowayanova.r
you will see it loads package lsmeans directly before using cld function

I updated lsmeans and run this part of the script again. Now i stil get the error. :frowning:

this is what appears in the console:

library("lsmeans")
> library("multcompView")
> 
> posthoc <- lsmeans(model1,
+            pairwise ~ object*tijd, 
+            adjust="tukey")
> posthoc
$lsmeans

Error in cld(posthoc, alpha = 0.05, Letters = letters) :

i guess i can manually check all of the contrasts but i'd rather have a clear graph or table printed . any other way to fix this ?

seems that cld is really a function of multcomp package, perhaps lsmeans just provides methods for it.
try to load the multcomp library
