[R] LSD comparison

[arun]

Hi,Without any reproducible example or code, it is difficult to understand the problem.  Did you load the package?
Using the example in ?LSD.test()
library(agricolae)
data(sweetpotato)
      model<-aov(yield~virus, data=sweetpotato)
      out <- LSD.test(model,"virus", p.adj="bonferroni",
      main="Yield of sweetpotato\ndealt with different virus")

Study: Yield of sweetpotato
dealt with different virus

LSD t Test for yield 
P value adjustment method: bonferroni 

Mean Square Error:  22.48917

Dear Sir 
  
I'm a student in the university and just start to use R for agricultural research analysis. 
I know my question is an old question, but I don't find any clear explanation about  my problem via internet. 
I'm sorry if my email is disturbing all of you. 
  
I install R with version 3.0.1 and no problem with anova analysis, 
my problem is I can't perfprm LSD comparison, it is appearing "Error: 
could not find function "LSD.test" 
I think I'm already installed "agricolae package" on my system. I attach some picture as shown on my screen. 
if possible please guide me  how to solve the problem. (how to check if agricolae package is completely installed?) 
  
Thanks you very much for reading
