Hi Arun, I will explain more clearly what I need.
Here I have an array MinMax with 2 column Max and Min MinMax â it is like Min Max ---- ------ 3 6 1 5 And I have an matrix with same dimension [same dimension is must] MyMatrix â ABC XYZ ---- ----- 4 6 7 3 [Condition : if the matrix values is not coming in between Min and Max value then give âRCâ] Here , in the next step , 1st row of MinMax values [Min=3,Max=6] will compare with 1st Column of MyMatrix [âABCâ] and as per that result will store as âRCâ in a new column [actual coulmnname with â_QFâ]. Like this, [Here in ABC Column, we are going to compare the values 4 & 7 with MinMax values 3 & 6 and result will put in ABC_QF column] [Same like above for next XYZ column]. Finally result will get like this form. ABC XYZ ABC_QF XYZ_QF ---- ----- ------ ------- 4 6 RC 7 3 RC Its urgent. -Thanks Antony.

For example, your statement ->"In this i need to check each particular column values are between Max and Min value. If the coulmn value not coming between Max and Min, then i need to create another coulmn" This implies to check for each columns in the dataset and create colname_QF My reply was based on these facts. As the Min and Max were assigned to 3 and 6, I was under the assumption that this is for the whole dataset. Then, you mentioned that it was only for column ABC. I guess the Min and Max were the ones you found from the original dataset for the first column. So, based on Min and Max for each column, your condition should be met. ->"If the coulmn value not coming between Max and Min, then i need to create another coulmn by adding column name header with "_QF". and assign a string like "RC" for that particular row." If that is the case, try the code below: #################### dat1<-read.table(text=" ABC XYZ PQR RDN SQT 2 4 3 2 8 5 4 8 3 9 7 1 3 4 1 3 2 4 3 2 4 6 5 7 4 ",sep="",header=TRUE) mindat1<-apply(dat1,2,min) maxdat1<-apply(dat1,2,max) minmaxdat<-data.frame(rbind(mindat1,maxdat1)) rownames(minmaxdat)<-1:nrow(minmaxdat) func1<-function(x,y,z) {ifelse(y[[x]] < max(z[[x]]) & y[[x]] > min(z[[x]]),y[[x]]<-"","RC")} dat2<-data.frame(sapply(names(dat1),function(x) func1(x,dat1,minmaxdat))) colnames(dat2)<-paste(colnames(dat2),"QF",sep="_") dat3<-data.frame(cbind(dat1,dat2)) dat3 ABC XYZ PQR RDN SQT ABC_QF XYZ_QF PQR_QF RDN_QF SQT_QF 1 2 4 3 2 8 RC RC RC 2 5 4 8 3 9 RC RC 3 7 1 3 4 1 RC RC RC RC 4 3 2 4 3 2 5 4 6 5 7 4 RC RC ################################################## A.K. ----- Original Message ----- From: Rantony <[hidden email]> To: [hidden email] Cc: Sent: Friday, July 13, 2012 2:42 AM Subject: [R] Column create and Update using function Hi, here i have a Max and Min values Min <-3 Max <-6 and also a matrix like this, ABC XYZ PQR ------ ------- ------- 2 4 3 5 4 8 7 1 3 In this i need to check each particular column values are between Max and Min value. If the coulmn value not coming between Max and Min, then i need to create another coulmn by adding column name header with "_QF". and assign a string like "RC" for that particular row. For eg:- i need to checkout coulmn "ABC". Here 2,5,6 are the values we need to checkout with Min,Max values. and here Min <-3,Max <-6 First need to create a new column called "ABC_QF" with current matrix. ABC XYZ PQR ABC_QF ------ ------- ------- ----------- 2 4 3 RC 5 4 8 7 1 3 Next, for 5 , it coming in between 3 to 6. so nothing to do. ABC XYZ PQR ABC_QF ------ ------- ------- ----------- 2 4 3 RC 5 4 8 7 1 3 Next, for 7 , its not coming in between 3 to 6. so put "RC" ABC XYZ PQR ABC_QF ------ ------- ------- ----------- 2 4 3 RC 5 4 8 7 1 3 RC ----------------------------------------------------------- This is the requirement. i did it using for-loop,it will check each value and it taking time when bulk of data come. Any hope to do using lappy,appy kind of functions ? Because at a time complete coulmn should get update. Could you please help me urgently ? - Thanks Antony. -- View this message in context: http://r.789695.n4.nabble.com/Column-create-and-Update-using-function-tp4636400.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ________________________________ If you reply to this email, your message will be added to the discussion below: http://r.789695.n4.nabble.com/Column-create-and-Update-using-function-tp4636400p4636552.html To unsubscribe from Column create and Update using function, click here <http://r.789695.n4.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&node=4636400&code=YW50b255LmFra2FyYUBnZS5jb218NDYzNjQwMHwxNTUxOTQzMDI5> .
