xd <- as.data.frame(x)
levels(xd$x) <- gsub("/", "-", levels(xd$x))
fix(xd)
This works fine .but with one more variable say xsd in the data
frame i'm
getting the following error
Error in levels(sa$date1) <- gsub("/", "-", levels(sa$date)) :
attempt to set an attribute on NULL
Are there two columns date1 and date in "sa"? Have you made a typo?
