Hi ,
When a R session runs , it creates a temporary directory . I am using
R_CleanTempDir() to clean it up . It looks like its not working properly .
So what exactly is going on here is , my example is
main()
start__R__Interpreter
while(1)
{
execute R scripts using R_parseVector
.
Thanks,

Hi ,
For our production package i need to create a dataframein C . So I wrote
the following code
SEXP dfm ,head,df , dfint , dfStr,lsnm;
*SEXP valueVector[2];*
char *ab[3] = {"aa","vv","gy"};
int sn[3] ={99,89,12};
char *listnames[2] = {"int","string"};
int i,j;
//
Thank you very much . I forgot one thing in my code
SET_TAG(CDDR(head), install("n")) ; after that it works
Thanks again,
Sandip

Hi ,
I am trying to call head function from C . My doubt is with the parameter

PROTECT(dfm=lang3(install("data.frame"),df,ScalarLogical(FALSE)));

I am asking too many questions , sorry for that . I am creating a data

I am concerned about the return value of typeof in character column in a
dataframe. I expect it to be of character ,it returns integer instead .

Is there any C API to the R API nrow of dataframe ?

The following C code may help you , time_t is typedef to long int

c_time_string = ctime(¤t_time);
return mkString(c_time_String); // or if you want to return as int
