QQ plot for normality testing
Hi all,
I am trying to test wheater the distribution of my samples is normal with QQ plot.
I have a values of water content in clays in around few hundred samples. Is the code :
qqnorm(w) #w being water content
qqline(w)
sufficient?
How do I know when I get the plots which distribution is normal and which is not?
Thanks, m

scatter plot with Z value
Hi all,
I would like to create a scatter plot of two variables (y, x) whith third value (z) written on the plot? After that i would like to add a line (Y=0.7*(x-20)) to the graph.
I tried
plot(x~y)
but there is no command for the third vairable to be shown on the graph
also i can't find a way to add a Y=x*(0.7-20) to the chart.
Thanks, m

subseting data
Hi,
Is it possible (i am sure it is) to subset data from a data.frame on the basis of SQL >LIKE< operator. I.e., i would like to subset a data where only values which contains a string >GP< would be used?
Example:
Gp<-subset(DF, DF$USCS like >GP<)
This like of course is not working,
Thanks, m

I wiuld like to compare the data to see which are more alike. I used the cluster analysis, but now i ma wondering if there are some other methods, since the cluster analysis did not give me the result i like.
I tried to use factanal() for factor analysis

Change panel background color in spplot()
Hi!
How does one change the background color of the map-panel in spplot()?
Example:
library(sp)
data(meuse.grid)
gridded(meuse.grid) = ~x+y
spplot(meuse.grid, "part.a")
How would I get another background-color for the map-panel (but not for
the whole plot) here?
Thank you!

side-by-side map with different geographies using spplot
Hello,
I want to create side-by-side maps of similar attribute data in two
different cities using a single legend.
To simply display side-by-side census block group boundary
(non-thematic) maps for Minneapolis & Cleveland I do the following:
library(rgdal)
library(sp)
Minneapolis=readOGR("../Minneapolis/Census/2010/Census_BlockGroup_GEO/","tl_2010_27053_bg10")

Mapa de quantiles con spplot
Hola,
Intento representar en un mapa participaciones porcentuales de los sectores económicos y no logro hacerlo con spplot.
He intentado con spplot(zm, c(?part88?, ?part93?), cuts=4, col.regions=brewer.pal(4, ?Set3?))
Lo pude hacer utilizando el base graphics de R, definiendo:
> plotvar88 <- zm$part88
> nclr <- 8
> plotclr <- brewer.pal(nclr, "PuOr")

make an own (different) color legend with spplot()
Hi!
Is there a way to manually costumize the color legend in an spplot() -
especially where to draw ticks and labels for the ticks?
The reason I'm asking: Usually spplot() automatically divides the data
into fitting slices and makes a color legend (also automatically).
I want to assign the slices myself and have a fixed scale instead of an
automatic/dynamic scale.
I think what I want

loop
Dear all,
I am trying to run a loop in my codes, but the software returns an error: "subscript out of bounds"
I dont understand exactly why this is happenning. My codes are the following:

mresultx <- matrix(-99, nrow=1000, ncol=nsim)
mresultb <- matrix(-99, nrow=1000, ncol=nsim)

using spplot (sp package) with 5 quantiles
Hi,
I'm using R 2.5.1 and gstat 0.9-39 library and I'm working with the
jura data set provided by gstat library.
I tried to plot a graph of metal concentrations (let's say Cd) with
the command spplot, but I realized that the default lags are equally
distributed between Min and Max. I did:
library(gstat)
data(jura)
jura.pred.xy <- jura.pred
names(jura.pred.xy)[1:2] <-

Buenas tardes,
Estoy probando a leer archivos netcdf (como raster stack) y crear
animaciones de datos de modelos climáticos y estaba utilizando para
generar las imágenes spplot(). Estás imágenes tienes superpuestas
varias capas de imagenes, el mdt de base, nubosidad, precipitación y
nieve. Mi pregunta es la siguiente,¿es posible visualizar la leyenda
de cada una de las capas?

Hola,
Lo hice de la forma en que propones y no me sale, no sé si algo esté mal con R, porque no me respeta ni el ?key.space?, me lo sigue poniendo en la parte izquierda del gráfico

lattice fun: multiple themes in panels with spplot()
I have some geospatial data where two layers are thematic and the third is a

Is it possible to create color ramp legend in spplot for discontinuous data ?
Hello All,
I have a discontinuous dataset and I used spplot to plot the points.
I was wondering whether it is possible to show the legend of the plot as
color ramp. I saw that on continuous data. If anyone could tell me that
would be great.
Another thing I would like to know is how can we create the horizontal
legend. By default, the legend is vertical.
I was able to shift the legend inside
