[R] write.dbf error: invalid subscript type 'list'

[Rui Barradas]

Hello,

It works with me,


d1 <- read.table(text="
ID simloglkhd
1 6.72782753120542
2 3.37685863056105
3 3.28498537979818
4 4.15888243774255
", header=TRUE)
d1
foreign::write.dbf(d1, "test.dbf")

d2 <- foreign::read.dbf("test.dbf")
identical(d1, d2) # FALSE
all(d1 == d2)     # TRUE

attributes(d1) # d1 doesn't have a
attributes(d2) # 'data_types' attribute

unlink("test.dbf") # clean-up


So maybe it's a R version/package version thing? I really don't know, 
try updating the package.
Also, use single forward slashes in the pathnames, the result is exactly 
the same, but more portable and less messy.

Hope this helps,

Rui Barradas
