Error Message: could not find function "daisy"

homework
package-installation

#1

I have installed the package "cluster" and then entered the following:

#convert the Gower dissimilarity object into a distance matrix
as.matrix(dist(Data))
Dist <- as.matrix(Dist)
#Gower similarity measure between the 10th and the 60th observation (row)?
d.data <- daisy(data, metric = "euclidean", data_frame (10,60))

I received the following errors:

Warning message: 
In dist(Data) : NAs introduced by coercion
> d.data <- daisy(data, metric = "euclidean", data_frame (10,60)) 
Error in daisy(data, metric = "euclidean", data_frame(10, 60)) : could not find function "daisy"

I don't understand why the function can't be found since I have installed the package "cluster". Is it because of where the default package directory has been installed?
