Hello, If I understand correctly, you are getting error messages when you have a lot of elements in the vector.
You can save your vector in a file.txt and use source() to call it. For. e.g. I saved a long vector (~1787 elements) in code.txt file. dat1<-source("code.txt") dat1<-dat1$value is.vector(dat1) [1] TRUE head(dat1) [1] "X12002" "X12027" "X12054" "X12084" "X12085" "X12115" A.K. ----- Original Message ----- From: chester123 <chester...@live.cn> To: r-help@r-project.org Cc: Sent: Monday, July 16, 2012 4:26 PM Subject: [R] about dpik Thank you for your reply. I know the x in dpik() means the vector. But I don't know how to import into c() with a huge metadata (>1000). Following is my some try, and the h is: [1] 0.001180569, which seems to be feasible. x<-c(-0.00109349389485645,-0.00145304131152137,0.00023685387037116,0.00579094886320110,0.00032117330426379,0.00363758302533228,-0.00113344327121731,0.00104726223729409) library(KernSmooth) h<-dpik(x,scalest="minim",level=2L,kernel="normal",canonical=FALSE,gridsize=401L,range.x=range(x),truncate=TRUE) h But the point is how to import more than 1000 numbers into the c() to vectorize them?
