This table is only in one column! I need to assign the variable age, to do the average, variance, ..., but I can not do this because they are in the same column.

Your data takes the form of a comma-separated file (csv), but with the presence of quotation marks for the values. I believe that a simple read.csv will not work (other suggestions are welcome).

One solution is to copy this data into a txt file and read with read.table . First let's read the file indicating the separation by space. In this way each element will contain the entire line of the data frame

# ler ficheiro (warning é devido a falta de estrutura do documento)
dados <- read.table('data.txt', sep = ' ')

# separar entre cabeçalho e dados
cab <- dados[1]
dados <- dados[-1]

Now let's separate each value separated by a comma with the function strsplit()

# separar cada elemento por vírgula
df <- data.frame(matrix(NA, nrow = 1, ncol = 15))
for(i in 1:length(dados)) {
  df[i, ] <- unlist(strsplit(as.character(dados[, i]), ','))
}

# incluir cabeçalho
names(df) <- unlist(strsplit(as.character(cab[, 1]), ','))

# transformar variáveis
for(i in c(4, 5, 6, 10)) {
  df[, i] <- as.numeric(df[, i])
}
