[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 level

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

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 a

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 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 7.

[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
