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

Hi,
Stackoverflow had an example. Forgot the contributor's name but it shows
percentages at the top. I use it as it is as I am not the expert.

pdata<-read.csv("histogram.csv",header=T)
histPercent <- function(x, ...) {
H <- hist(pdata$y, plot = FALSE)

Hi,
I came across the integration package that lets a Java
program interact with R. Does any one use this model for simulation ? I

Hi,
I understand that R can be used to plot correlated values using a
Multi-parameter histogram. We have authorization requests and response
and they are correlated because a response is governed by a SLA. Is it a
good use case for using R to correlate these requests and responses ?

Hi,
I plot no: of bytes against time and find the distribution
curve using R. These bytes are sent from the client to the server.
Is there a way to generate bytes randomly using R according to a
distribution ? I would like to send these bytes to the server. Hope I am

I have been asking only general questions even though I am using

I am a new user and this is a basic question. I have read the
