Hi,
Can a Matlab code be converted to R code?
I am finding it difficult to do so.
Could you please help me out with it.
Your help will be highly appreciated.

1. Yes. Both are Turing complete .
2. Someone here may be willing to help you if you're lucky, but the
standard recommendation is: Do your homework and learn R! (There are
many good tutorials and resources available).
3. In future, post in plain text, not HTML, as the posting guide asks.
Hello
I wonder what the formula behind as.numeric(2012-11-11 19:05:00 UTC”) is.
Many thanks

No formula behind that:

[1] NA
Warning message:
NAs introduced by coercion
If a character string is recognizable as a number, you get that number.
For example:
as.numeric('3')
[1] 3
But your character string isn't recognizable as a number, so you get NA,

k - which(df4$id==2)
df4[k,c3] - df4[k,c2”]

Hi
Thanks for data
df4$c3[df4$id==2] - df4$c2[df4$id==2]
is one option
df4$c3 - ifelse(df4$id==2, df4$c2, df4$c3)
If you have NA values you shall use which like in
sel - which(df4$id==2)
df4$c3[sel] - df4$c2[sel]

I try to superimpose/present 2 curves/plots on the same graph. I would like the

For that, I use the par(new=TRUE) argument but on the Y-axis there is a

You do not say why you want to convert. I your reason is that you do not
have access to Matlab you might try to run your program in Octave. I think
that there are some syntax errors in your Matlab code. Most of these, but
not all, I think, may have been caused, (as you have already been told) by
Hi,
If he wants the two sets of data plotted on the same y axis scale, with the
range of the y axis adjusted to the data, an alternative to the use of plot()

See ?matplot

Here is how:
plot(Date,MORTSFr,type=l, ylim=c(0,max(MORTSFr)))
points(Date,MORTSBu,type=l,lty=2)
If you don't use the same scale for the two plots, you are probably
misrepresenting the data. If you want to plot relative change, normalize the
data before plotting.
