Re: [R] R help: fviz_nbclust’ is not available (for R version 3.5.2)
Indeed, if you repeat the code you provided before then the problem will not go
away because you are not using the knowledge we have given you. You need to
show us what you are trying differently based on the explanations provided on
the mailing list. If you don't do this then we cannot move forward to more
specific answers.

Re: [R] R help: fviz_nbclust’ is not available (for R version 3.5.2)
Thanks for your valuable clarifications.
I tried all the steps again but the problem remains.
In fact, "fviz_nbclust" is a function inside the package "factoextra".
I run each step very carefully but the problem remains...It doesn't
make sense because I have installed factoextra.
This warning appears:
could not find function "fviz_nbclust"

Re: [R] R help: fviz_nbclust’ is not available (for R version 3.5.2)
Concept 1: You don't install functions... you install packages that have
functions in them. There is a function fviz_nbclust in factoextra.
Concept 2: Once a package is installed, you do NOT have to install it again,
e.g. every time you want to do that analysis. Making the installation part of
your script is not advised.
Concept 3: Typically we do use the library function with a package name at the
beginning of every session where we want to use functions from that package.
However, that is optional... you could also just invoke the function directly
using factoextra::fviz_nbclust(...blahblah...). Having the library function
shortens this and if the package is not installed it provides a clear error
message that can be a reminder to the user to install the package.
Execute your code line by line and solve the first error you encounter by
examining the error message and reviewing what that line of code is designed to
do.

Re: [R] R help: fviz_nbclust’ is not available (for R version 3.5.2)
Hi,
fviz_nbclust is a function within the package factoextra. Once you
have installed the package and loaded it, you do not need to
explicitly install the function.
You probably also don't need FunCluster - I think you may be confusing
that package with the FUNcluster argument to the fviz_nbclust
function.
Do take a look at
?fviz_nbclust
for help and a working example.
library(factoextra)
library(NbClust)
# Standardize the data
load("df4.rda")
fviz_nbclust(df4, FUNcluster, method = c("silhouette", "wss", "gap_stat"))

[R] R help: fviz_nbclust’ is not available (for R version 3.5.2)
Hello,
I'm struggling to install a function called "fviz_nbclus".
My code is the following:
pkgs <- c("factoextra", "NbClust")
install.packages(pkgs)
library(factoextra)
library(NbClust)
# Standardize the data
load("df4.rda")
library(FunCluster)
install.packages("fviz_nbclust")
#fviz_nbclust(df4, FUNcluster, method = c("silhouette", "wss", "gap_stat"))
Installing package into ‘C:/Users/DELL/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘fviz_nbclust’ is not available (for R version 3.5.2)
Best,
Meriam
