Re: [R] Error in if loop
Dear Mark,
Thanks for this. Can you please explain me what is the difference between
ifelse and if?
generally if there is more than one syntax within the 'if' I use 'if' loop
otherwise I use 'ifelse' loop. Is it the only difference between them?

There are 3 issues here:
1. Do you appreciate the difference between ifelse and if ? What are
you actually trying to do - in this context, ifelse would usually be
more sensible but as you've not said what you want to do, it is
difficult to guess.
2. I don't get the same error as you. Which version of R are you using?
> if (name=="v")
+ {
+ u=0
+ }
> else u=1
Error: syntax error
This error message makes it clear that there is a syntax problem. In
fact, look at the lefthand column of characters and you should see
what the problem is
3. R is interpreting your code as two separate expressions because you
are using an interactive shell. Try this instead:
if (name=='v') {
u=1
} else {
u=0
}
Hope this helps.
Best wishes,
Mark

[R] Error in if loop
I have created a if loop as follows:
name = "e"
if (name == "v")
{
u = 0
}
else u = 1
however i am getting error : Error: unexpected 'else' in "else"
definitely I can write in : ifelse() form, however I want to write in this
way. Can anyone tell me where is my error?
thanks in advance

[R] Sample selection problem
I want to get a sample of some arbitrary size from a population having only two values 0 and 1 with replacement, but with different probability for selection. For example 0 will be selected with probability 0.4 and 1 with 0.6. I could use sample function i.e. sample(c(0,1), 30, T) to get this, however here, selection of either 0 or 1 has equal probability here. I am looking for a function which can do the same thing but with different probabilities. - Meet people who discuss and share your passions. Join them now.

[R] Expressing number in percentage

[R] Legend
I have following syntax for putting a legend :
legend("bottom", fill=c("red","blue"), legend=expression(p==0.30, p==0.50),
bty="n")
However what I want is that : the value "0.30" should be a value of a variable
instead of a constant, so that I can put the name of this variable and in
legend it's value will be displayed. Can anyone tell me how to do that?
Regards,
thanks in advance
