Need Help!

Dear Sir/Madam,
 
I hope you will be fine. I am new to R language. Recently, I am trying to fit my data with one model.
I am sending you the code and image file on which you can see the error I am receiving instead of executing.
If I give a single value to parameter "ep", it executes well, but if I make a loop/seq for getting a range of data it shows
error.I need you help in solving this problem.
 
Thanking in advance,
 
With Best Regards,
Dawood

Dear Dawood,

it is not a really good idea to open a new email with the same problem you already posted earlier.
I see you accepted some suggestions (HTML, seq) but not others (pi is a defined constant in R, do not change it, type pi ENTER to see this.). I would like to add one more, c is a function, do not use it as a variable name (I used cc instead of c).
I tried to figure out what you want here. The following code might do what you want. It gives you a feeling about how you would create a basic loop. There are nicer ways to do that in R. Note the [i]-s in the for loop!


cc <- 0.5
xc <- 2
s <- 6
Hc2 <- 30
H <- 1
ep<-seq(0.01, 0.49, by=0.001)
res <- numeric(length=length(ep))

for (i in 1:length(ep)){
  f<-function(k) 1.211*10^(-6)*Hc2/H*(trigamma( ((ep[i] + H/Hc2 + (2*xc/s)^2*(1 - cos(k*s))/2)/2*Hc2/H)) -  trigamma(((cc + H/Hc2 + (2*xc/s)^2*(1 - cos(k*s))/2)/2*Hc2/H)))
  res[i] <- integrate(f,-pi/s,pi/s)$value
}

Best,
daniel

Dear Daniel,
 
Thank you very much for such a kind reply. Actually, I couldn't understand well the criteria of help list, I am 
sorry for that. I tried you method, unfortunately I couldn't get the output. It may be due to my lack of expertise in programming. At this point I need your help which will mean a lot to me. Moreover, if I use single value it gives the output. I am sending you two image files of the outputs. I will be really grateful to you if you guide me.
 
Thanking in advance,
 
With Best Regards,
 
Dawood

For crying out loud Dawood - can you please stop posting screenshots? Do you not know how to copy your output and paste it into the body of a (not HTML formatted!) email? Let us know if you need help with that.

Hi,

type
res #<ENTER> (now it contains your results as a vector)

or

head(res) #so you only see the first couple of values

or

plot(res) #to see a basic plot (you could set axis labels etc, but I suggets you to go ahead and read a tutorial on R!

Best, have a great time with R,
kd
