HI Jackson,
This might get you started:
# plot a few squiggles
plot(runif(100)+1,seq(1,0,length.out=100),xlim=c(1,6),
type="l",main="Squiggles by Years",
xlab="Squiggles",ylab="Years",xaxt="n")
lines(runif(100)+2,seq(1,0,length.out=100))
lines(runif(100)+3,seq(1,0,length.out=100))

Hi Ravi,
Try this:
current_customer<-0
for(row in 1:dim(A)[1]) {
if(current_customer == A$Customer[row]) {
if(A$Time_Diff[row] > 12) A$flag_1[row]<-1
else A$flag_1[row]<-A$flag_1[row-1]+1
}
else {
current_customer<-A$Customer[row]
A$flag_1[row]<-1
}
}

This assumes that the data are sorted by customer, and that only the
first value of Time_Diff is missing for each customer (and that the
first value is always missing for each customer). If those assumptions
hold you can do something like
A <- read.table(text = "customer Time_Diffflag_1

Dear Roger,
Thank you for your email.
I am sorry for HTML containing email. I am not very good in IT so I
didn't know that my email client is using HTML by default. Now I have
tried to turn it off and I would be very grateful if you could let me
know if it is all right now.
Regarding my question
Hi,
I am trying to apply the below logic to generate flag_1 column on a data
set consisting of ~1.2 million records in R.
Code :
for(i in 1: nrows)
{
if(A$customer[i]==A$customer[i+1])
{
if(is.na(A$Time_Diff[i]))
A$flag_1[i]

I don't think we can do a lot with Q1 without some data. Data would probably
help with Q2 as well. Have a look at the following links especially on how to
use dput() to supply sample data.

Hi everybody,
I need help to plot (question 1) and to extract information from another
plot (question 2). Could anyone help me? I will be very grateful.
I do not know if I could enclose a figure here, so I saved it in my dropbox

You could use Rmarkdown, and use as output: html.

Hi,
when you can plot this graph using the rgl-package,
then you can use "rgl::writeWebGL" to create an 3D-View
in the Browser.

Hi Georgia,
In that case you are conducting an exploratory analysis, sometimes called a
fishing expedition, on the effect of location. The usual procedure is to
plot the populations by the areas and put the Mark I human eyeball to work.
If you see some pattern that you can plausibly defend, such as

Not sure if my post was accepted. Try running R from your desktop but right
clicking on the icon and selecting "Run as Administrator", rather than opening

Good luck,

I want to put a graph in a html5 webpage plotted with R (I want to get dar

F.e NYSE:C
Does everybody know how to plot (with code) un html5 to plot trough R o
directly plot the sale plot with monthly data?
I Hope you can help me explosing an example.
Hi Jim,
I just tried the code and it worked perfectly! You brought me a huge step
nearer to my bachelors degree ;) thank you very much!

Here's one way to save your results, using a list of lists and a for() loop.
nsim <- 100
outputs <- vector("list", nsim)
for(i in 1:nsim) {
outputs[[i]] <- sim.f(p.s=.05, N=1000, sample.size=69, n.sim=500)
}

Besides this, using bounds to fix (also called "mask") parameters is
generally a very bad idea. Some optimization methods allow this
explicitly. For nonlinear least squares nlmrt package has it, but I'm
not sure I fully documented the process. For optimization, Rvmmin and
Rcgmin both allow mask
You need to read the help more closely. start should be a list, as you've
done, but upper and lower should be vectors instead. Which is exactly what
your error message is telling you.

vectors of lower and upper bounds, replicated to be as long as start. If
