[R] Gamma Simulation from Exponential Distribution: find sample size given power and sig.Level

I built my function to simulate two gamma distributions X and Y based on the sum of i.i.d exponential distributions. Assume my code is correct about this simulation, I am interested in finding an equal sample size n for X and Y such that n can be determined given 90% power and 5% significance

[R] How to take ID of number 7.

I figured out something new that I would like to see if I can do this more easy with R then Excel. I have these huge files with data. For example: DataFile.csv ID Name log2 1 Fantasy 5.651 2 New 7.60518 3 Finding 8.9532 4 Looeka -0.248652 5 Vani 0.3548 With like header1: ID, header 2:

Re: [R] compare mean

I am also compairing 2 things with each other. x = c(1, 5, 7, 9) y = c(2, 7, 9, 10, 11) intersect(x, y) Output will be: 7, 9. Hope it helped. :) -- View this message in context: http://r.789695.n4.nabble.com/compare-mean-tp4576372p4578007.html Sent from the R help mailing list archive

Re: [R] How to take ID of number 7.

O_o This is kinda interesting I have 267 log2 values = 7. And 295 ID numbers. I don't see any problems in my code also: ID_Log2_Above_7 = DataFile[DataFile$log2 = 7, c(ID, Log2] # Take ID out. ID_Above_7 = ID_Log2_Above_7$ID # Only numbers, no na or inf. ID_Above_7_NO_NA =

[R] Sort out number on value

Can anyone help me maybe with a question I can seem to find an answer on. I have this: x = c(1, 5, 70, 53, 7, 29, 75, 37, 30, 11) And I would like to have the numbers above 20 selected out. But I can't find what code I need for that I tried sort(), but then I can't fill in I only need

Re: [R] Re : Sort out number on value

I found out something strange when I used the same thing on another data file. In a excel file I have same data too and there I asked in a certain column what values where above the 7.5. Result: 206. Now I have done the same thing in R and I get as result: 400. My code: # Find values above

Re: [R] Re : Sort out number on value

I see the problem. There are 400, but there are Na and Inf is there for like 1/2, and I need to get those out. Think I need to filter those out. Now that would make sense. LoL -- View this message in context: http://r.789695.n4.nabble.com/Sort-out-number-on-value-tp4573467p4573905.html Sent

Re: [R] Re : Sort out number on value

I now filtered the Na and Inf out of my data. And the number is exactly the same als the output from the excel file. Thanks everyone. :) Now I can finish my work. -- View this message in context: http://r.789695.n4.nabble.com/Sort-out-number-on-value-tp4573467p4574026.html Sent from the R

[R] How insert data to a column in existing csv file?

I was working with some excel files with a lot of data. And by hand it is impossible to handle them. So they are now converted to .csv. With headers above the columns, like: Data1, Data2, Data3 But now I needed to calculate the log2 value of Data1 and place the result under Data2. I can't

Re: [R] How insert data to a column in existing csv file?

Hi everyone, I read your messages and I tried some things out. The Data2 is filled with NA. So what I did was: NameFile.csv$Data2[is.na(NameFile.csv$Data2)] = log2Values And now it worked. :) Seems like I needed to replace it, and not only write it. Thanks. -- View this message in
