[SOLVED] Duplicate

[dimitridor]

Hello,

Using duplicate, I get the following error :

Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 4920, 6767

Hereunder, you'll find the characteristics of my databases. This function was working in a previous version of RGeostats (v11.1). Was there a change in its code in the last version (v11.3) ?

Thank you for your help,

Dimitri

Hi Dimitri

Unfortunately, I cannot exhibit such an error on the data sets that I can generate quickly.
I probable need that you send me the two Db (possibly you can save them in ASCII format using db.write) as well as the duplicate syntax ... by mail.

Cheers

Hello Didier,

Thanks for your answer.

Here is a sample code producing the error:

nrow=100
c=matrix(nrow=nrow,ncol=3)
c[,1]=runif(nrow)
c[,2]=runif(nrow)
c[,3]=rnorm(nrow)

A=db.create(c)
A=db.locate(A,2:3,"x")
A=db.locate(A,4,"z")

nrow=20
d=matrix(nrow=nrow,ncol=3)
d[,1]=runif(nrow)
d[,2]=runif(nrow)
d[,3]=rnorm(nrow)

d=rbind(d,c[1:20,])

B=db.create(d)
B=db.locate(B,2:3,"x")
B=db.locate(B,4,"z")

X=duplicate(A,B, print=TRUE)

Result:

Error in data.frame(..., check.names = FALSE) :
arguments imply differing number of rows: 100, 40

and db X is not created.

Does it help you to identify the problem?

Hello Dimitri

I checked with your data set (thanks for providing it). As a matter of fact, you pointed a bug.
The "duplicate" function returns a selection vector that should be added to the SECOND db (not the first one as pretended in the help).
The code had to be fixed in a future release. If you need an urgent version, please let me know.
Thanks
Didier

Hello Didier,

Your answer lets me know the new bug may be linked due to the correction applied after an former bug I posted with the title: "[SOLVED] Erreur de sortie dans duplicate ?"

I need this functionality for a big project with an important deadline in September. I will be on vacation from Friday till around the 20th of August. Is it possible to get the correction these days so that I can continue? Otherwize, having the new version by August 20th will be fine.

Cheers,

Dimitri

Hi Dimitri

I do not want to publish an official new version now (I am in the process of coding a new neighborhood option). But I can certainly send you a link to a temporary version (that I can easily build for LINUX). If for WINDOWS, we will have to wait for the new official version ... probably early August.

Didier,

I'm working on Windows... So, let's wait August for the new version.

Thank you for working on it.

Bests,

Dimitri
