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.
replace_string.sh
#!/bin/bash
for db in $(find /var/www/html/web -name * -exec)

sed -e "s/old1/new1/" \

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

using the following R statements:

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

How to remove autocorrelation from a time series?
Dear R users,
someone knows how to remove auto-correlation from a frequencies time series?
I've tried by differencing (lag 1) the cumulative series (in order to have only positive numbers) , but I can't remove all auto-correlation.
If it's useful I can send my db.
x <- # autocorrelated series
new1<-cumsum(x)
new2<-diff(new1,lag=1,differences = 1)
acf(new2) #

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?

by length class (eg. of 5cm) and get the mean value of all the other variables (eg VarA and VarB) for each length class
My dataframe is as follow:
Length <- 10:30
VarA <- seq(1000,1200,10)
VarB <- seq(500,700,10)
Data <- cbind(Length,VarA,VarB)
