When replacing all elements of a column in a data.frame, a corrupt data.frame
will be generated if the replacer is "short":
test> bbb <- data.frame( x=1:2)
test> bbb[,'x'] <- 3 # should fill the column
test> bbb
x
1 3
2 <NA>
Warning message:
corrupt data frame: columns will be truncated or padded with NAs in:
format.data.frame(x, digits = digits)
test> bbb$x
[1] 2
This works OK in R 1.7.1 and also for matrices in R 1.8. Although there have
been a number of deliberate changes to data.frame subscripting in R 1.8, I
suspect this one isn't intentional!
NB still happens in 1.8.1 alpha
