write.dbf error: invalid subscript type 'list'

Hey,

Strangley, this is working

foreign::write.dbf(df,"H:\\CIV\\CIVProject\\DATA\\plotdata.dbf")

and this is not

library(foreign)
write.dbf(df,"H:\\CIV\\CIVProject\\DATA\\plotdata.dbf")

Maybe it is the syntax? Can you please test this..?

Thanks

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,

Dear all,

I am basically a GIS user and am new to R.

I am trying to write a data frame to a dbf file.

*n.simulations <- 999

binomial <- kulldorff(geo, cases, population, NULL, pop.upper.bound,
n.simulations, alpha.level, plot)
cluster <- binomial$most.likely.cluster$**location.IDs.included
df <- data.frame(ID=seq(1,n.**simulations,by=1),
simloglkhd=binomial$simulated.**log.lkhd)

write.dbf(df,"H:\\CIV\\**CIVProject\\DATA\\plotdata.**dbf")*


I am getting this error.

*Error in c<logical="L", integer="N",numeric="F",**charachetr="C", :
   invalid subscript type 'list'
Calls: write.dbf -> <Anonymous>*

If I added *

write.dbf(df,"H:\\CIV\\**CIVProject\\DATA\\plotdata.**
dbf",factor2char=TRUE,max_**char=254)
*

Now, I get error as these are unused arguments.

If I write it to text file using write.table, the text file looks like
this.

*"ID" "simloglkhd"

"1" 1 6.72782753120542
"2" 2 3.37685863056105
"3" 3 3.28498537979818
"4" 4 4.15888243774255
.
.
.*


Can anyone please tell me what am I doing worng?
