if else and loop for code in R
I am using if else and loop to sortout the data set that is the values
less than o or more than 100 will be chosen.I could not get outTable
with loop.
Please help me to correct the code:
I USED:
# Read
a_data <- read.table("D:/SNP/copy.sas", header=T, sep="\t")
tr <- a_data$truck
ca <- a_data$cars
length <- nrow(a_data)
outTable <- matrix(nrow=length,ncol=3)

when I convert it to transaction class:
as(a_data.frame, "transactions")
All columns are grouped together under items, which is like this:
{sequenceID, eventID, items}
instead of the right form: sequenceID, eventID...

original frame, but are dropped when applied to a new frame.
ultimately I need to cbind the residuals and predictions to a dataframe.
Any help would be appreciated. Thanks in advance.

Dear all,
I may have overlooked something but the following piece of code causes me
trouble:

Is this the fact my data.frame has only one dimension ?
(and do I forget somewhere (but where ?) to specify not to 'drop'
dimension or s...

Overriding default DELETE behavior with logical deletes
Hello!

physical deletes using ActiveRecord. Basically, in many applications
that deal with E-Commerce, you really can''t physically delete almost
anything, because records must be kept for auditing and customer service
