[R] counting characters starting point

I have three character strings represented below as seq1, seq2, and seq3. Each string has a reference character different from the other. Thus, for seq1, the reference character is U, seq2, S (3rd S from left where A is leftmost character) and for seq3 Y. seq1 = PQRTUWXYseq2 = AQSDSSDHRSseq3 = E

[R] Split a list

I have a list of dataframes i.e. each list element is a dataframe with three columns and differing number of rows. The third column takes on only two values. I wish to split the list into two sublists based on the value of the third column of the list element.  Second issue with lists as well. I

[R] bootstrapping nonlinear mixed effects models

In order to bootstrap nonlinear regression, the following code works. library(nlme) data(Soybean) fm1.nls <- nls(weight ~ SSlogis(Time, a, b, c), data=Soybean) summary(fm1.nls) bstat <- function(A, indices) { mboot <- nls(weight ~ SSlogis(Time, a, b, c), data=Soybean[indices, ]) return(coef(mb

[R] How to get "mypkg-manual.pdf"

I am building a package say mypkg. Five months ago, when I built the package I got the mypkg manual in pdf format. Today, after making updates, I build the same package, same name, and steps; unfortunately I do not get the manual in pdf format. Rather I get the following message: cd: can't cd

[R] Reducing a matrix

I wish to rearrange the matrix, df, such that all there are not repeated x values. Particularly, for each value of x that is reated, the corresponded y value should fall under the appropriate column. For example, the x value 3 appears 4 times under the different columns of y, i.e. y1,y2,y3,y4.

[R] Rearranging entries in a matrix

I have a matrix, called data. I used the code below to rearrange the data such that the first column remains the same, but the y value falls under either columns 2, 3 or 4, depending on the value of z. If z=1 for example, then the value of y will fall under column 2, if z=2, the value of y falls
