Terrific! How could I've missed that. Well, I know, I didn't get it from the
documentation...

Thanks

or more simply, just use equilogs=FALSE in the grid call:

plot(seq(1,9), log="x", panel.first=grid(equilogs=FALSE))

Use abline instead of grid for fine tuning:

plot(seq(1,9), log="x", panel.first=abline(v=c(1,2,5),h=c(2,4,6,8), 
lty=3,col="gray"))


or more simply, just use equilogs=FALSE in the grid call:

Of course the option "nx" in grid() is not valid, as it does not align the
grid lines with the ticks in a log scale...
 
Thanks for giving a hand.

[R] grid lines aligned on each ticks with a log scale

for publication purpose I must provide a graph with grid lines aligned with

Thing is that the graph has a log scale on the x-axis.
I looked at the grid() and par() documentation but still don't figure out

[R] Grid lines in cloud plot for lattice

[Chris Jones]

Hi all,

I was wondering if there was a way to draw out grid lines in the cloud  
plots for lattice. I hunted all throughout the panel.cloud and panel. 
3dscatter help pages and couldn't find anything to help me move  
forward with this. Do I have to get deeper into the drawing commands,  
or is there something more obvious I'm just not seeing? My goal would  
be to place grid lines on the bottom face of the box and make drop  
lines to the grid.


#example dat set
nirK.env.nmds$points = cbind(rnorm(30),rnorm(30),rnorm(30))

par.set <-
 list(axis.line = list(col = "transparent"),clip = list(panel =  
"off"))

print(cloud(nirk.env.nmds$points[,3]~nirk.env.nmds$points[, 
1]*nirk.env.nmds$points[,2],
 col="red",pch=16,cex=1.5,type=c("p","h"),
 strip = strip.custom(strip.names = TRUE),
 scales=list(arrows=FALSE,distance=2),
 xlab="NMS 1",
 ylab="NMS 2",
 zlab="NMS 3"),
 par.settings=par.set,
 split = c(1,1,2,1), more=TRUE)

Many thanks!!

(1) How can I put the legend on top of the grid lines?

(2) How can I match the grid lines with the x-axis ticks?

(3) How can I change the x-axis format from e.g. Mar, Apr...etc to
1-3-2009,1-4-2009...etc?

Many thanks! :-)

Example for your loop:

for (i in c(1:n)){
file.name=f[i]
dat<-read.csv(file.name,header=F)
colnames(dat)<-c("obsTime","obsHead","comTime","comHead")
obsTime<-as.Date(dat$obsTime,origin=model.startdate)
comTime<-as.Date(dat$comTime,origin=model.startdate)

### omit x axis at first:
plot(obsTime,dat$obsHead,main=file.name,xlab="Date",ylab="Hydraulic 
Head (mAHD)",col="blue",ylim=c(ymin,ymax), xaxt="n")


### add x axis with given format and save the locations:first:
xticks <- axis.Date(1, obsTime, format = "%d-%m-%Y")
lines(comTime,dat$comHead,col="red")

### add you self designed grid:
abline(v=xticks, h=axTicks(2), lty=1, col="darkgray")

### legend with white background at the end:
legend("bottomright",legend=c("Observed Head","Computed 
Head"),col=c("blue","red"),lty=c(0,1),pch=c(1,-1), bg="white")



### forget about:
#grid(lty=1,col="darkgray")
}

It probably is on top. I guess you want white background as in:

legend(., bg="white")



(2) How can I match the grid lines with the x-axis ticks?



grid() does exactly that for me, so I guess you are not using base 
graphics, hence please provide reproducible code as the posting guide 
suggests!




(3) How can I change the x-axis format from e.g. Mar, Apr...etc to
1-3-2009,1-4-2009...etc?



One way is to specify the x-axis separately, but since we do not know 
how you produced that plot

You've obviously done some tinkering with the plot function, but I
don't know which of the dozens of possible ways you used to do that,
so I can't tell what adjustments are needed.  There are some people on
this list who are good at guessing, but it would make it easier for
you if you told us.  The operative phrase is 'reproducible code' and
there's a few more of them in the footer of every message from this
list.
