Hi Jhancarlos, welcome!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Thanks for your attention,

For example if you use the comand:

data("spainfoot") you get a table where the first column are the names of the football teams

but when I import an excel dataset the first column is a set of numbers (1,2,3,4..n)

That is not a column, those are row_names, Excel doesn't understand that concept that is why you get (1, 2, 3, ..n).

You could manually assign any column as row_names if you need to for some reason, see this example

library(dplyr)
df <- iris %>% group_by(Species) %>% summarise_all(max) %>% as.data.frame()
df
#>      Species Sepal.Length Sepal.Width Petal.Length Petal.Width
#> 1     setosa          5.8         4.4          1.9         0.6
#> 2 versicolor          7.0         3.4          5.1         1.8
#> 3  virginica          7.9         3.8          6.9         2.5
rownames(df) <- df$Species
df
#>               Species Sepal.Length Sepal.Width Petal.Length Petal.Width
#> setosa         setosa          5.8         4.4          1.9         0.6
#> versicolor versicolor          7.0         3.4          5.1         1.8
#> virginica   virginica          7.9         3.8          6.9         2.5
