ggplot plot error in R

Question

I am tryong to use ggplot in my data, but i get this error:

##Don't know how to automatically pick scale for object of type function. Defaulting to continuous Error in data.frame(x = .Primitive("length"), fill = c(6L, 5L, 7L, 3L, : arguments imply differing number of rows: 0, 245

I am trying this command: ggplot(all, aes(length, fill = NLABfather)) + geom_density(alpha = 0.2)

Adaptaded from this topic How to plot two histograms together in R? (choosed aswer)

My all dataframe look like that:

value NLABfather
0.13 NE001362 0.17 NE001361 0.05 NE001378 -0.12 NE001359 -0.14 NE001379 0.13 NE001380 -0.46 NE001379 -0.46 NE001359 -0.68 NE001394 0.28 NE001391 0.84 NE001394 -0.43 NE001393 -0.18 NE001707 -0.47 NE001380 0.10 NE001362 -0.10 NE001381 0.08 NE001711 -1.15 NE001707 0.07 NE003322 -0.12 NE001394 0.19 NE001358 -0.61 NE001360 -0.12 NE001362 0.07 NE001394 0.10 NE001386 -0.53 NE001380 0.05 NE001380 -0.43 NE001362 -0.10 NE001395 -0.20 NE001389

Answer 1

Your data frame column is called value but you've put length in your function call.

 ggplot(all, aes(value, fill = NLABfather)) + geom_density(alpha = 0.2)

produces something.
