Hi All,
Just thought you might be interested in a recently released R package, spm:
Spatial Predictive Modelling.
It aims to introduce some novel, accurate, hybrid geostatistical and machine
learning methods for spatial predictive modelling.
Of 22 functions available in spm, two functions ar

Thanks. I will try that and see if I can get it to work. I am working on a
vignette for a package. I should have been more careful in my wording, it was
really a RMarkdown question, not specifically an RNotebook question. I will
leave to others to decide if that implies R content, I am jus
Hi Ace,
You can just read the file first to find out:
max_fields<-function(file,sep=" ") {
rlines<-readLines(file)
return(max(unlist(lapply(sapply(rlines,strsplit,sep),length
}
nmax<-max_fields(test.txt,"\t")

Although it is not an elegant solution, but if your output format is
HTML, you can add an arbitrary empty HTML element like before your code chunk. Then you can jump to this
via a link like "see [this code chunk](#foo)".

Hi All:
In creating a R Notebook I know that in the text I can link to a (sub) section
by using the command:
[Header 1](#anchor)
and putting the appropriate anchor name at the appropriate header. But can
the same be done for code chunks, if the code chunk is named? What I want to

I did not put the double quotes in the SQL statement. The SQL statement was
created automatically by the routine dbWriteTable.
The full code (minus the details of creating the DBIConnection object)
would be like this, as in the man page for dbWriteTable
library(DBI)
library(odbc)
conn <- [connect
Double quotes are not legal SQL syntax. Use single quotes.

I have been successfully using RODBC for a long time (years) to connect to
MS SQL Server from R.
This week I wanted to try using odbc but I am seeing some problems which
may be related to how I set up my driver and/or connection.
The dbWriteTable manual page gives as an example command:

Thank you for the kind reply.
1. The order of the dimension is reflected when used as print(ncin)
function. This function has been used to have a quick look at the structure
of the default netCDF file.
2. Firstly, I am in need of subsetting this netCDF file and then have to
convert the slice into .
