search for: ltext

Hi all (really probably just Deepayan): In the plot below I want to add text on either side of each violin plot that indicates the number of observations that are either positive or negative. I'm trying to do this with ltext() and I've also monkeyed about with panel.text(). The code below is generally what I want but my calls to ltext() are wrong and I'm not sure how to fix them. Right now they replicate the first column of the matrices obs.pos and obs.neg for each panel. How do I tell ltext to advance to the n...

ltext( 0, 0, pos=NULL, label="xxxx") gives an error message. The help page of ``ltext'' references to the help page of ``text'' where the default value of pos is set to NULL. To solve the problem ``ltext'' could be changed: OLD: if (!missing(pos)) NEW: if (!mis...

Dear friends - please give me a hand. I have a dataset of 40 patients in two groups observed on three occasions. I only want to plot a line for each patient in the two groups. I use the ltext function to put the patient number but fail to make lattice understand the numbers as unique since apparently it starts all over with 1:20 for each panel instead of respecting my desires to have 1:20 and then 21:40. I'm on windows vista, R2.9.2 Best wishes Troels score <- runif(120,0,...

What I'm looking for is to write the text always in the same position along the panels, say in the middle of each panel something like "ltext(x = 1.5, y = (ylim[2] - ylim[1])/2 )" I tried to play with "ylim" and prepanel but unsuccesfully.

Hi. I have been able to get things like text(9,46, expression(hat(beta) == (X^t * X)^{-1} * X^t * y)) to work in regular plots but ltext(9,46, expression(hat(beta) == (X^t * X)^{-1} * X^t * y)) does not do the same in lattice (trellis) plots. Has it not been implemented or am I missing something? Thanks - Mary -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.c...

I am drawing a density histogram, and want to label the plots with the mean using ltext(). But I need the x,y coordinates to feed into ltext, and I can't calculate them easily from my data. Is there a way to get the x and y ranges being used for the plot, so I can put the text at the correct position in the panel.function? Thanks, Jim Rome

Hi, Can anyone please help me with how I could add labels with the value for each bar in a barchart?

Dear r-help I draw plots with xyplot() function. Each plot contains also a line of regression. I want to write the trend value and its significance (obtained with lm()) below each panel. I use ltext() for this. But the text is cut, when it comes outside a panel. Moreover (obviously), it doesn't appear at all when its coordinates are outside a panel. Could you, please, be so kind to give me a direction to walk in order to have a text written below a panel. Thank you! --...
