use 'lapply' to creat 2 new columns based on old ones in a data frame
There is a dataset 'm', which has 3 columns: 'index', 'old1' and 'old2';
I want to create 2 new columns: 'new1' and 'new2' on this condition:
if 'index'==i, then 'new1'='old1'+add[i].
'add' is a vector of numbers to be added to old columns, e.g. add=c(10,20,30
...)
Like this:
index old1 old2 new1

replace multiple string
Hi
I would like to use a bash script that searches files and
subdirectories name in a directory /var/ww/html/web
for a specific string, and when it finds the search string, replaces
the string (old1) with new string (new1), and so on
old2 with new2 ....oldn with newn.

convert characters into integers in a matrix
Hello,
I will appreciate any suggestion for this simple problem. I have a matrix of
characters "A", "P", "M".
I want to convert those characters to integers 0,1, 1 respectively. I am
using the following R statements:
exprs.new<-gsub("P",1,exprs)
exprs.new1 <- gsub("A",0,exprs.new)
exprs.new2 <-

fill an array by rows
I've dug around but not been able to find anything, am probably missing
something obvious.
How can I fill a three-dimensional (or higher dimension) array by rows
instead of columns.
eg
new1 <- array(c(1:125), c(5,5,5))
works fine for me but fills it by columns and
new2 <- array(c(1:125), c(5,5,5), byrow=TRUE)
throws an error.
Am I missing something obvious? I also tried

nlminb--lower bound for parameters are dependent on each others
Hello
I'm trying to solve two sets of equations (each set has four equations and
all of them share common parameters) with nlminb procedure. I
minimize one set and use their parameters as initial values of other set,
repeating this until their parameters become very close to each other.
I have several parameters (say,param1, param2) and their constraints are
given as inequality and depend

[PATCH 2/10] linux 2.6.18: COMPAT_VDSO
This adds support for CONFIG_COMPAT_VDSO. As this will certainly raise
questions, I left in the code needed for an alternative approach (which
requires mode C code, but less build script changes).

cannot delete the last column of a dataframe using "[<-" (PR#9565)
Hi,
If df is a dataframe, its last column can't be deleted using "[<-", but
other columns can be deleted this way.
Example:
> (df <- df0 <- data.frame(x = 1:3, y = 4:6, z = 7:9))
x y z
1 1 4 7
2 2 5 8
3 3 6 9
> df[, "z"] <- NULL
Error in x[[jj]] : subscript out of bounds
> df[, 3] <- NULL
Error in x[[jj]] : subscript out of bounds

Problem running stepAIC within a function.
Hi
I need to a function that automatically fits a regression to data, using the
stepAIC. I've ran the code manually and it works fine. However, when I run
the function on the same data, the following error occurs:
Problem in regimp(fullsim = simt, fullsim1 = simt1,..: Length of (weights)
(variable 4) is 4271 != length of others (4278)
I got the function to output the length of the dataset

request for patch in "drop1" (add.R)
By changing three lines in drop1 from access based on $ to access
based on standard accessor methods (terms() and residuals()), it becomes
*much* easier to extend drop1 to work with other model types.
The use of $ rather than accessors in this context seems to be an
oversight rather than a design decision, but maybe someone knows better ...
In particular, if one makes these changes (which I am

Best way to split forms into steps?
I have a form with about 30+ fields, which the client is wanting to
separate into 3 pages/steps - just wondering what is the best way to go
about this, specifically remembering data entered, from one page to
another, and making sure the various bits of data are validated
correclty, error messages outputted etc etc...
is there a best practice method for doing this?

Cropped graph using lattice
I'm fitting data from a mixture experiment, and I'd like to present the results in a ternary graph with contours. I found this code by Walmes Zeviani
http://n4.nabble.com/Triangular-filled-contour-plot-td1557386.html
which is just what I want--except I would like the axis titles and labels to be proportionately larger than the ternary graph itself, for legibility in publication. When I
