Which columns are used in kmeans algorithm in R, as there are no arguments for designating columns?
0
Says, a dataframe df_1 has 8 columns, and following code is used.
res = kmeans(df_1, 4, nstart=40)
The K-means clustering result is stored in res.
In most examples, two dimensions (i.e. two columns) are used to demonstrate the clustering.
However, in the above code, df_1 has 8 dimensions.
How do I know, which columns were used?

@sai sara, I did not check any sheet. I just did some research online and no example showed the criteria of the input data.frame.

Description Perform k-means clustering on a data matrix. Usage kmeans(x, centers, iter.max = 10, nstart = 1, algorithm = c("Hartigan-Wong", "Lloyd", "Forgy", "MacQueen"), trace=FALSE) ## S3 method for class 'kmeans' fitted(object, method = c("centers", "classes"), ...)

They will all be used. If you want to use only certain columns then limit the columns in the data frame that you pass to the kmeans function
