I have tried every way to fit a Lowess curve, a local regression smoothing technique, into this distribution. I used the following code:
library(dplyr)
library(tidyr)
library(ggplot2)
dados <- dput(AIG)
dados %>%
mutate(id = row_number()) %>%
gather(semana, tamanho, -id) %>%
mutate(semana = factor(semana, levels = c("X26", "X27", "X28", "X29",
"X30", "X31", "X32", "X33", "X34", "X35", "X36", "X37", "X38", "X39", "X40")))%>%
ggplot(aes(x = semana, y = tamanho ,group = id)) + geom_point(na.rm = TRUE) + geom_smooth(method = "loess") + ggtitle('Gráfico do grupo AIG')
But I only get the following graph:
I'm using the ggplot2 library, but no problem if you can help me fit that curve into another library.
