Hi

How about ...

# Data

lines = "Col1 Col2 Col3 Col4

Text1 Text2 X0.1 5
Text1 Text2 X0.2 10
Text1 Text2 X0.3 15
Text1 Text3 X0.1 5
Text1 Text3 X0.2 10
Text1 Text3 X0.3 15"

# Create Dataframe

DF <- read.table(textConnection(lines), header = TRUE, check.names = FALSE)

# Create Numeric Variable

DF$Col5 = as.numeric(sub("X","",DF$Col3))

HTH Pete
