#R version 3.5.2 (2018-12-20)
#Platform: x86_64-w64-mingw32/x64 (64-bit)
#Running under: Windows >= 8 x64 (build 9200)
Hello I am working through this tutorial
https://www.r-bloggers.com/10-tips-for-choosing-the-optimal-number-of-clusters/
And I run into an error almost immediately at the point below like this:
mammals <- raw_mammals %>% select(-name) # set rownames
#Error in select(., -name) : object 'p_links' not found
I have googled the error " R object 'p_links' not found"
https://stats.stackexchange.com/questions/113907/error-object-descr-not-found
However, the links I have found seem to be specific to an object that has been
declared by the Op, and in my case I do not know where this object is supposed
to be coming from?
I think this stems from the use of the dplyr Pkg?
https://dplyr.tidyverse.org/reference/select.html
Here is what I have so far:
#Data Set
# I will be using a lesser known data set from the cluster package:
all.mammals.milk.1956, one which I haven't looked at before.
#
# This small dataset contains a list of 25 mammals and the constituents of their
milk (water, protein, fat, lactose, ash percentages) from John Hartigan,
Clustering Algorithms, Wiley, 1975.
#
# First let's load the required packages. Some of these are already in my
library, those that are not were installed
library(tidyverse)
library(magrittr)
library(cluster)
install.packages("cluster.datasets")
install.packages("NbClust")
install.packages("clValid")
install.packages("ggfortify")
install.packages("clustree")
install.packages("ggiraphExtra")
library(cowplot)
library(cluster.datasets)
library(NbClust)
library(clValid)
library(ggfortify)
library(clustree)
library(ggiraphExtra)
library(dendextend)
library(factoextra)
library(FactoMineR)
library(corrplot)
library(GGally)
library(knitr)
library(kableExtra)
data("all.mammals.milk.1956")
raw_mammals <- all.mammals.milk.1956
str(raw_mammals) #----------------------KNOW THY DATA
# 'data.frame':25 obs. of 6 variables:
# $ name : chr "Horse" "Orangutan" "Monkey"
"Donkey" ...
# $ water : num 90.1 88.5 88.4 90.3 90.4 87.7 86.9 82.1 81.9 81.6 ...
# $ protein: num 2.6 1.4 2.2 1.7 0.6 3.5 4.8 5.9 7.4 10.1 ...
# $ fat : num 1 3.5 2.7 1.4 4.5 3.4 1.7 7.9 7.2 6.3 ...
# $ lactose: num 6.9 6 6.4 6.2 4.4 4.8 5.7 4.7 2.7 4.4 ...
# $ ash : num 0.35 0.24 0.18 0.4 0.1 0.71 0.9 0.78 0.85 0.75 ...
#raw_mammals <- fread("Animal Milk Constituent
Percentages.csv",header=TRUE, stringsAsFactors=TRUE)
# subset dataset
mammals <- raw_mammals %>% select(-name) # set rownames
#Error in select(., -name) : object 'p_links' not found <--The Error
I hope this is enough information to help answer my question.
Thank you

I'm not getting any error on that line in Windows 10. I did not try running
anything past that line.
Have you tried restarting R and clearing your environment?

Another possible issue could be some outdated packages... be sure to update all packages.
