[R] Reordering the columns of my dataframe

Hi R-helpers, I have written this line of code: data-cbind(data[,1],data[,2:6],data[,18],data[,7:17]) to reorder the columns of my dataframe, but I'm losing the column names of my 1st and 18th columns (they are now named data[,1] and data[,18] respectively). Can I use cbind to do this

Re: [R] Searching for specific values in a matrix

no luck, it's okay, i will figure it out! i might isolate and recombine all the columns, maybe that will work. thanks for the help! No, wait .. no luck in being able to select out rows from your data.frame using values you see somewhere in the top 10 rows? Can you just paste in some key

[R] Splitting matrix into several small matrices

Dear R users... I need to split this matrix(or dataframe), for example, z - matrix(c(13,1,1,1,1,12,0,0,0,0,8,1,0,1,1,8,0,1,0,0, 10,1,1,1,1,3,0,1,0,0,3,1,0,1,1,6,1,1,1,1),8,5,byrow = T) z [,1] [,2] [,3] [,4] [,5] [1,] 131111 [2,] 12000

[R] Draw plot.table axis on right hand side

With an ordinary plot, to customise the axis it is possible to suppress drawing the axis and then call Axis. I have been trying to change the location of the y-axis on a plot.table plot to the right hand side, but cannot even work out how to suppress drawing the labels. Here is a toy example of

[R] Double Truncation Fit??

Hey guys, Do you all know of a function that provides fitting for double-sided truncation? truncreg accounts for one-sided truncation, but not two, or at least I don't how to. Our outlier values are -115 on the left side and -55 on the right. Help appreciated, Vivek

Re: [R] Split rownames into factors

Hi, I'm not an R expert, but I thought I'd give your question a shot anyway. First, it looks like you're starting with a matrix, rather than a list. Let's hope I guessed that right: m = matrix(c(324, 65, 543, 23, 54, 8765, 213, 43, 65)) rownames(m) = c('X1Jan08', 'X1Jun08', 'X1Dec08',

[R] frequent sequences

Hello, I'm having a few issues mining frequent sequences. I've read the documentation and played around with arules and arulesSequences with little success. For example if I have a vector, a = t(t(c(1,2,3,0,1,2,3,5,6,7))); I'd like to be able mine the association rules {1,2}--{3}, {2}--{3},

Re: [R] Non-Linear Regression with two Predictors

Hi and thank you for your reply, in my new regression formular the parameter delta is inserted: fit - nls(dataset$V2~(( alpha / ( 1 + exp( beta - gamma* dataset$V1 ) ) ) + (dataset$V6*delta)),data=dataset,start=startparam) The sense is, that dataset$V6 is a dummy variable that represents the

the problem is, it works with the example data i gave. however, it does NOT work with the data set i have, which is 600,000 rows. the class is still a data frame. On Mon, Jul 27, 2009 at 12:15 PM, Steve Lianoglou mailinglist.honey...@gmail.com wrote: On Jul 27, 2009, at 2:54 PM, Mehdi Khan
