Hi,

I am trying to train svm with some training data of about 4000 rows and 4000
columns. While running svm function I am ending up with the following error.

trainfile <- read.csv('0_train_0016435.csv',head=TRUE,na.strings = "NULL")

datatrain <- subset(trainfile,select=c(-Class))

model <- svm(datatrain, kernel="radial")
Error in FUN(newX[, i], ...) : 'x' is empty

I tried substituting "NULL" strings in the data with some numeric values but
still I am ending up with error as:

model <- svm(datatrain, kernel="radial")
Error in FUN(newX[, i], ...) : missing observations in cov/cor
In addition: Warning message:
In FUN(newX[, i], ...) : NAs introduced by coercion

Could you please help me in finding out where I am going wrong.

Thanking you in advance.
