R data preparation for cluster use

Navigation
2

I have a database, where in the first column are some basketball teams and the following columns are some observed variables. I would like to do a cluster analysis using such packages: 

library("cluster") ;
library("factoextra") ;
library("magrittr")

Database:

Whenreadingmydatabasethatwasincsv,Iturneditintoadata.frame,butinanattempttoscalethevariableswiththecodebelow,thiserrorappearssayingthatmy"Time" column should be numeric and thus consequently I can not also do the correlation matrix because in the label some random numbers appear instead of the name of the teams.

ERROR 

my_data <- na.omit(my_data)
my_data <- scale(my_data)


Error in colMeans(x, na.rm = TRUE) : 'x' must be numeric

CORRELATION GRAPHIC ERROR 

res.dist <- get_dist(my_data, stand = TRUE, method = "pearson")
fviz_dist(res.dist, gradient = list(low = "#00AFBB", mid = "white", high = "#FC4E07"))

Does anyone know how to solve this?

As Rui said in the comment, the image of your data does not help us to help you. As for doubt, the scale function needs your bank to be a numeric array. One solution is to transform the column with the name of the teams in the name of the lines: 

row.names(my_data) <- my_data[,1]
my_data <- my_data[,-1]

and then move on with your code. Probably the second mistake will not happen again.
