Hi all, Before posting to r-bugs, I thought that I would just verify this one first. It looks like the help for axTicks() needs to be corrected. It presently says: 'axTicks()' can be regarded as an R implementation of the C function 'CreateAtVector()' in '..../src/main/graphics.c' which is called by 'axis(side,*)' when no argument 'at' is specified. However, CreateAtVector() is actually in '..../src/main/plot.c' (line 684) instead. It is referenced in graphics.c. In r-devel's plot.c, it is at line 69...

...x,y, log = "y", ylim = c(1,30)) However, plot(x,y, log = "y", ylim = c(30,1)) fails with Error in axis(2, ...) : log - axis(), 'at' creation, _SMALL_ range: invalid {xy}axp or par; axp[0]= 10, usr[0:1]=(34.3721,0.872801) In addition: Warning message: CreateAtVector "log"(from axis()): usr[0] = 34.3721 > 0.872801 = usr[1] ! According to Petr Pikal <petr.pikal -at- precheza.cz>, replacing the ylim argument by ylim = c(30,1.2) helps in the above example; but in my real world applications, it's actually difficult to find a working value f...

Hi, I am new to R plot. I am trying to scale my y axis in log. When I do this I receive the following error Error in axis(side = side, at = at, labels = labels, ...) : CreateAtVector [log-axis()]: axp[0] = 0 < 0! In addition: Warning messages: 1: In plot.window(...) : nonfinite axis limits [GScale(-inf,1.31772,2, .); log=1] 2: In axis(side = side, at = at, labels = labels, ...) : CreateAtVector "log"(from axis()): axp[0] = 0 ! My code is as follows: foundO...

Hi, I get a lot of error messages with this command, but I don't understand why; plot(c(),c(), xlim=c(1,10), ylim=c(0,10000), log="y") thanks for any help! [[alternative HTML version deleted]]

...x,y, log = "y", ylim = c(1,30)) However, plot(x,y, log = "y", ylim = c(30,1)) fails with Error in axis(2, ...) : log - axis(), 'at' creation, _SMALL_ range: invalid {xy}axp or par; axp[0]= 10, usr[0:1]=(34.3721,0.872801) In addition: Warning message: CreateAtVector "log"(from axis()): usr[0] = 34.3721 > 0.872801 = usr[1] ! What am I doing wrong here? Thanks a lot, Christian.

...etty(), with the user able to specify how many intervals using "grid.inc", with a default of 5 as in pretty(). If anyone has any better thoughts on how to approach this, I am open. I was trying to figure out a way to call the C code in plot.c that generates the default axis intervals (CreateAtVector), but would get errors indicating that the function is not in the load table. This would seem to be a cleaner approach at first glance, since it would result in consistent default axis interval behavior when not plotting grid lines. I am open to pointers or other thoughts on this. Finally, t...
