Hi,
Try this:
myMatrix<-read.table(text="
Name??????????? Age
ANTONY??????? 27
IMRAN????????? 30
RAJ????????????????? 22
NAHAS????????? 32
GEO??????????????? 42
",sep="",header=TRUE)
MinMaxArray? <- data.frame(MIN = 25,MAX=35)
myMatrix[myMatrix$Age<=MinMaxArray$MAX & myMatrix$Age>=MinMaxArray$MIN,]
? #? Name Age
#1 ANTONY? 27
#2? IMRAN? 30
#4? NAHAS? 32

#or
subset(myMatrix,myMatrix$Age<=MinMaxArray$MAX & myMatrix$Age>=MinMaxArray$MIN)
#??? Name Age
#1 ANTONY? 27

Subject: [R] Remove a complete row as per the Range in a Matrix

Hi,

Here i have a Matrix

MyMatrix <- 

Name? ? ? ? ? ? Age 
---------? ? ? ? ?  -------
ANTONY? ? ? ? 27
IMRAN? ? ? ? ?  30
RAJ? ? ? ? ? ? ? ? ?  22
NAHAS? ? ? ? ?  32
GEO? ? ? ? ? ? ? ?  42

and here i have an array with Minimum and Maximum values.
MinMaxArray? <- data.frame(MIN = 25,MAX=35)
MIN? ?  MAX
------? ?  --------
25? ? ? ? ?  35
------------------------------------------------------
Now what is, i need to get a matrix by removing the rows which is NOT coming
the "Age"-column in between the MIN and MAX value.? Is it possible to avoid
"for-loop", bcz its a huge matrix.

so, final matrix looks like this,

Name? ? ? ? ? ? Age 
---------? ? ? ? ?  -------
ANTONY? ? ? ? 27
IMRAN? ? ? ? ?  30
NAHAS? ? ? ? ?  32


- Thanks in advance,
Antony.
