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.
