similar to: 2 plots 1 figure

Hello, I am a new user. I would like to know if it is possible with R to fix the position of ticks. for example for my plot I obtained automatically the positions 200,400,600,800 and 1000 on x axis and so a scale of 200 But I would like to obtain 100,200,300,400,500,600,700,800,900,100 so a scale of 100. Which fonction can help me to do so? thank you meriema

Hello I have used recently the kolmogorov smirnov test, which is a test of normality. This test is named ks.test() in ctest library of R. I wonder if the results of ks.test () are true, because the results are strange, time to time. thank you for help meriema -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi, I have a transaction block as follow: begin Hello.transaction(input1,input2) input1.save for i in 0 to count input2[i].input1_id = input1.id input2[i].save end end rescue end I have used validates_uniqueness_of for input2 in the model The problem is, when there is duplicate record in input2, input1 and the first record in input2

hello, here are some problems with ks.test. Do you think these values are consistent? (2 e^{-1} means 0.2 ) data file name& sample size& D & pvalue A&10.000&0.4202&<2.2 e^{-16}\\ B&10.000&04294&<2.2 e^{-16}\\ C &10.000&0.4484&<2.2 e^{-16}\\ D&10.000&0.4569&<2.2 e^{-16}\\ E&50.000&0.4015&<2.2 e^{-16}\\

Hi, We are experimenting directly generating vectorized LLVM IR (using <8 x float> kind of types), then compiling the code to SSE on a 64 bits machine. Right now the equivalent code in scalar mode sill outperform the SSE one. What is the quality of the SSE support in X86 LLVL backend? Are they any specific things to be aware of to improve the speed? Thanks Stéphane Letz

Dear R helpers   I have some variables say ABC, DEF, PQR, LMN and XYZ. I am choosing any three varaibles at random at a time for my analysis and name these files as input1.csv, input2.csv and input3.csv. So if I choose variables say ABC, DEF and PQR, I am passing the specifications of these variables to input1.csv, input2.csv and input3.csv respectively.   This means in another case even if I

Hello All, I'm trying to create a matrix from a dataframe (let's call it df): ......a......b.....c.....d a inputs output b inputs output c inputs output d inputs output e inputs output The inputs are represented by columns a and b The outputs are represented by columns c and d, but the only outputs are those from column d - some values from column d are

I want to use var.test function of ctest library. I was able to generate the output from R on the input given by rnorm. But when I store the same data set provided by rnorm into a file, and then read a file into a dataframe, then on using the dataframe as a parameter to var.test function - it gives an error "not enough x observations". I'll explain the above mentioned problem of

Dear members, I have started to work with R recently and there is one thing which I could not solve so far. I don't know how to define macros in R. The problem at hand is the following: I want R to go through a list of 1:54 and create the matrices input1, input2, input3 up to input54. I have tried the following: for ( i in 1:54) { input[i] = matrix(nrow = 1, ncol = 107)
