What does this error mean [R Programming]?-CodePudding

My data frame

> dput(wt)
structure(list(Teams = structure(1:21, .Label = c("Arsenal", 
"Aston Villa", "Bournemouth", "Brighton", "Burnley", "Chelsea", 
"Crystal Palace", "Draw", "Everton", "Leicester", "Liverpool", 
"Man City", "Man United", "Newcastle", "Norwich", "Sheffield United", 
"Southampton", "Tottenham", "Watford", "West Ham", "Wolves"), class = "factor"), 
`Total Number Of Wins` = c(6L, 6L, 5L, 6L, 7L, 11L, 7L, 50L, 
 7L, 14L, 18L, 14L, 8L,7L, 3L, 7L, 7L, 8L, 4L, 6L, 7L)), class = "data.frame",                                              
 row.names = c(NA, -21L))

My pie ggplot code

pie = ggplot(wt, aes(x="", y="Total Number of Wins", fill="teams"))   geom_bar(stat='identity',width = 1)

pie = pie   coord_polar("y", start=0)   geom_text(aes(label = paste0(round(value*1), "%")), position = position_stack(vjust = 0.5))

The error i get is 'Error in paste0(round(value * 1), "%") : object 'value' not found'. What should I replace the 'value' with ? Can someone please enlighten me

CodePudding user response：

I'm not sure what you are trying to achieve here, but it looks like its because "value" here, which you used in your code, doesn't have an assigned variable. I basically loaded the data you had and saved one variable to make it work:

value <- wt$`Total Number Of Wins`

Then printed the plot using the same plot script you used:

pie = ggplot(wt, 
             aes(x="",
                 y="Total Number of Wins", 
                 fill="teams"))   
  geom_bar(stat='identity',
           width = 1)

pie = pie   
  coord_polar("y", 
              start=0)   
  geom_text(aes(label = paste0(round(value*1), 
                               "%")), 
            position = position_stack(vjust = 0.5))

Which gave me this:

I think what you meant to do was color code this, and you just need to make one more minor edit. R is case sensitive, so you need to capitalize the "Teams" variable in your original pie code:

pie = ggplot(wt, 
             aes(x="",
                 y="Total Number of Wins", 
                 fill=Teams))   # capitalized variable w/o quotes
  geom_bar(stat='identity',
           width = 1)

Which if you now run both plot codes, itll give you this:
