R help - Oct 2020 - Good Evening,

I contacted Martin Maechler (maechler at stat.math.ethz.ch) and was advised to
contact you for input on the question below...thanks!

I am very new with the R experience, all I know is that it's computer
language & coding... I'm trying to plot a regression graph for runif
(100,
1000, 10000). What am I not getting here, I can get the values in R no
problem, but no idea how to turn it into a graph... No idea how to
determine the X or Y axis...etc.
Any assistance will be appreciated...Much Thanks!
Thanks,
*Joy (B.) Kissoon* (Ba.So.Sc.-Criminal Justice, Nurse, Artist)

Hello,

To plot a graph you don't need to compute the axis, R will do it for you:

# create data
set.seed(2020)    # Make the results reproducible
x <- runif(100, 1000, 10000)


This is not very intuitive but the following will plot the x values in 
the y axis, along the x axis values 1 to 100.


plot(x)


To plot a regression line you will need a regression model and that 
means you need a response variable.

y <- x + rnorm(100)

model <- lm(y ~ x)
plot(x, y)
abline(model, col = "red")



The question is very basic, you should focus on learning a bit more of 
R. Start with R-intro.pdf that comes with R. There are also many texts 
online that cover this and lots of other graphics stuff.


Hope this helps,

Rui Barradas

Hi Joy,
As Rui noted, you can get a plot with:

jk.dat<-runif(100,1000,10000)
plot(jk.dat,type="l")

This plots your vector of 100 uniformly distributed numbers against their
"index" (the order in which they appear in the vector). I suspect your
problem is that you want to define a vector of "x" values that will
attach
them to a real set of observations. Say that you are preparing to work with
the daily counts of cosmic rays for a neutron monitor.

obs_dates<-as.Date(as.Date("2020-07-23"):as.Date("2020-10-30"),
 origin=as.Date("1970-01-01"))
plot(obs_dates,jk.dat,type="l",main="Daily CR counts")

That may give you some ideas.

Jim
