I'm trying to make graph thanks to ggplot and shiny by using a csv file with data about food. The following code is working well.
p <- ggplot(data=Aliments, aes(x = Glucides, y = Proteines))
p <- p + geom_point()
p
However, the columns used to make the graph can change, the user has to decide. That's why i have to use this kind of code.
t <- c("Glucides", "Proteines")
p <- ggplot(data=Aliments, aes(x = t[1], y = t[2]))
p <- p + geom_point()
p
But t[1] is a str, and t[1] isn't recognize as the name of a column. Have you got an idea for this small problem ?
