Hi,
This is the code to create a ggplot. The plot is rendered but the y-axis
labels are not continuous. So the lines are split.
Moreover multiple y-axis labels overwrite each other due to this. How can I
fix this?
If I try to set ylim I get "
*Discrete value supplied to continuous scale"*
library(RJSONIO)
library(ggplot2)
this.dir <- dirname(parent.frame(2)$ofile)
setwd(this.dir)
airlines = fromJSON("json")
df <- sapply(airlines$data,unlist)
df <- data.frame(t(df))
colnames(df) <- c( (airlines[[1]][[1]])[[2]],
gsub("[^A-Z]","",(airlines[[1]][[2]])[[2]]),
gsub("[^A-Z]","",(airlines[[1]][[3]])[[2]] ),
gsub("[^A-Z]","",(airlines[[1]][[4]])[[2]]), (airlines[[1]][[5]])[[2]],
(airlines[[1]][[6]])[[2]], (airlines[[1]][[7]])[[2]],
(airlines[[1]][[8]])[[2]],
(airlines[[1]][[9]])[[2]],(airlines[[1]][[10]])[[2]] )
df.melted <- melt(df, id = "YEAR")
print(ggplot(data = df.melted, aes(x = YEAR, y = value, color = variable))
+geom_point() + theme(axis.text.x = element_text(angle = 90, hjust = 1)) +
ylab(""))
dev.off()
> head(df)
