R help - Aug 2017 - Annotation Ticks on the axis

Hi all,

I would like to have help in getting annotation ticks (corresponding to the
minor grid) on my plot. Here is my toy example :


par(mar=c(5, 6, 5, 5) + 0.1)

x<-1:10

y<-x^2

plot(x,y,log="xy",xlab="log(x)",ylab="log(y)")

par(new=T)

plot(log(x),log(y),type='n',col="red",xaxt="n",yaxt="n",xlab="",ylab="")

axis(side=3,tick=TRUE,at=pretty(range(log(x))))

mtext("log(x) with log labels",side=3,line=3)

axis(side=4,tick=TRUE,at=pretty(range(log(y))))

mtext("log(y) with log labels",side=4,line=3)

par()


I have the following questions :

1. I get a long output after the final par command. How can I make this
output silent?

2. I would like to get ticks corresponding to the command
annotation_logticks in ggplot2. Actually, it would be easiest for me to
work directly with ggplot. But I am not able to implement the secondary
axis option with ggplot. Would appreciate help with that, if it is easier.

Thanks,

Vivek

Hi,
Thanks for the quick answer. I looked into the link that you provided. But
I am still not able to implement a solution. Here is my attempt :

library(ggplot2)
x<-1:10
y<-x^2
df<-data.frame(x=x,y=y)
p1<-ggplot(df,aes(x,y))+geom_point()+
  scale_x_log10(
    breaks = scales::trans_breaks("log10", function(x) 10^x),
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  ) +
  scale_y_log10(
    breaks = scales::trans_breaks("log10", function(x) 10^x),
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  ) +theme_bw()
p2<-p1 + annotation_logticks()
p2


p2 + scale_y_continuous(sec.axis = sec_axis(~.))
I get the following error :
Scale for 'y' is already present. Adding another scale for 'y',
which will
replace the existing scale.

My questions :
1. How do I change the breaks and labels to correspond to those in my
earlier plot with R graphics? I don't want the 10^x format.
2. When I try with the annotation_logticks('trbl') option in the above
code, I get the error :
Error in base - 1 : non-numeric argument to binary operator
3. I don't see how I can use the secondary axis option. I can see how I can
multiply the y-variable (or x) by a constant ( e.g. by sec_axis(~.*10)).
But I don't see how I can use it with a function. For example, with log or
exp.
4. How can I create extra space in the margins with ggplot? Would the par()
command work here as well?

Would appreciate continued help.
Thanks
