r - ggplot gives "arguments imply differing number of rows" error in geom_point while it isn't true - how to debug? -



r - ggplot gives "arguments imply differing number of rows" error in geom_point while it isn't true - how to debug? -

i have 2 objects of type large spatialpointsdataframe named st2 , st10. come same source. both plot without problems with:

plot(st2)

or

plot(st10)

but want plot them ggmap , ggplot. can st2 simple code this:

map <- get_map(location = 'poznań', zoom = 12) ggmap(map) + geom_point(aes(x =st2@coords[,1], y = st2@coords[,2]))

but when comes st10 error:

error in data.frame(x = c(16.910848618, 16.910863876, 16.910913467, 16.910936356, : arguments imply differing number of rows: 53885, 4

i check values length():

> length(st10@coords[,1]) [1] 53885 > length(st10@coords[,2]) [1] 53885

i check them summary()

> summary(st10@coords[,1]) min. 1st qu. median mean 3rd qu. max. 16.84 16.88 16.91 16.91 16.91 16.99 > summary(st10@coords[,2]) min. 1st qu. median mean 3rd qu. max. 52.35 52.41 52.46 52.44 52.46 52.46

what wrong? have on 20 of sp info frames , of plot other give error mentioned above...this not related number of points

what can wrong? or maybe can give me tips how can debug this?

i got around making new info frame.

tldata=data.frame(x=c(0,100000),y=c(0,1000000) ggplot(otherdf,aes(x=x,y=y)+geom_point(alpha=0.1)+geom_line(data=tldata,aes(x=x,y=y),color='red')

it seems ggplot no longer likes have data-less geom components, prior version used okay using aes(x=c(0,100000),y=c(0,100000).

r spatial ggplot2

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
