New Eyes Needed to See Syntax Error
...many scripts to produce 4 lattice plots on one page keeps throwing
an error. I've tried manipulating the file to eliminate the error, but have
not been able to do so. The error is:
> source('bicarb.R')
Error in source("bicarb.R") : bicarb.R:15:1: unexpected symbol
14: 15: hco33
^
The 'h' is in column 0 so the caret would be column -1, but it's presented
as column 1. The file, bicarb.R is:
hco31 <- qqmath(~ HCO3 | factor(basin), data = surfchem.cast, main =
'Bicarbonate (Raw)',
prepanel = prepanel.qqmathline,
panel = function(x, ...)...

3D scatter, groups, RdbiPgSQL...
...om a PostgreSQL database (using the Rdbi and RdbiPgSQL
packages) it gives me this error message:
ERROR:
groups variable must be a factor.
To be more clear here is a command I used with the scatter3d (exactly
the same for the both datasets):
scatter3d(br_scatter$cl, br_scatter$br, br_scatter$hco3, fit="linear",
residuals=TRUE, bg="white", axis.scales=TRUE, grid=TRUE,
ellipsoid=FALSE, xlab="cl", ylab="br", zlab="hco3", groups =
br_scatter$stratigraphy)
the dataset I used is here (the same is the data imported from the CSV
file and from a...

gathering denominator under frac
...(frac("additive BIC","true BIC")))) worked OK - but
now I have been asked to put the chemistry instead - so I wrote
?ylab(expression(paste(frac("additive",HCO[3]^"-","true",HCO[3]^"-"))))
- and frac saw that as additive = numerator and HCO3- = denominator and
the rest was ignored-
So how do I make frac ignore the first ","? and print the fraction as I
want?
All best wishes

Sobre data.table
Mª Luz,
si el comando de Carlos te devuelve 0 es que no hay NA's.
Da igual que tus columnas sean caracteres o número.
Lo que intuyo es que tienes celdas con la frase "NA" que interpretas como NA.
Mandanos el summary de tu data.table y lo vemos...
