Can this loop be delooped?
Hi.
I have the following code in a loop. It splits a vector into subvectors of
equal size. But if the size of the original vector is not an exact multiple
of the desired subvector size, then the first few subvectors have one more
element than the last few. I know that the cut function could be used to
determine where to break up the vector, but it doesn't seem to provide
control over

If else statements
Hi everyone!
May I request again for your help?
I need to make some codes using if else statements...
Can I do an "if-else statement" inside an "if-else statement"? Is this the
correct form of writing it?
Thank you.=)
Example:
for (v in 1:6) {
for (i in 2:200) {
if (v==1)
(if max(x*v-y*v)>1 break())
if (v==2)
(if max(x*v-y*v)>1.8 break())
if (v==3)

Create NA
Hi,
How can I create an NA?
for example, i have this program but it has errors
> x=scan()
1: 1 2 3 4 5
6:
Read 5 items
> "na"*x
Error in "na" * x : non-numeric argument to binary operator
what should I multiply x so that I will get an NA? And I really need to
multiply that with my x vector.
I need this output: (na,na,na,na,na)
Thank you for your time and help!=)

Summing with NA
Hi all,
May I request for your help if you have time and if you have an idea on how
to do this. I want to add three vectors... And my goal is to obtain the sum
of the vectors, ignoring the vector of "na"...
Here is what i did in R.. I'm adding the three vectors, e,z,k, and my
objective is to get an answer = -23.
I tried putting the na.omit but it did not work. Thanks.

estimating NA values against selected slots
Dear R Users,
Could you please help me on the following issue?
I have a real large yearly data set. For each year I have
365 flow values. Some of the flow values are not known and that’s why you will
see NA written in those slots. I wanted to know, is there a way that I can
estimate those values? I tried approx command but it seems least helpful for
the kind of issue I am up against.

Cosinor
Hola, ¿qué tal?:
Tengo la siguiente duda:
Para el caso del Cosinor Simple:
Y = M + A * cos(2*pi*t/T + phi) + error
Cuando T conocido, podemos asumir:
Y = M + beta * X1 + gamma * X2 + error,
siendo X1 = cos(2*pi*t/T) y X2 = sin(2*pi*t/T)
En este caso (Cosinor simple) el modelado lo llevo a cabo del siguiente modo:
lm( y ~ X1 + X2)
Para el caso de componentes múltiples:

How to get the rowindices without using which?
Hi,
I was wondering if it is possible to get the
rowindices without using the function "which" because
I don't have a restriction criteria. Here's an example
of what I mean:
# take 10 randomly selected instances
iris[sample(1:nrow(iris), 10),]
# output
Sepal.Length Sepal.Width Petal.Length Petal.Width
Species
