How do you exit a function in R?
For example, based on a certain condition, I may want to exit my code early:
# Are there the same number of assets in "prices" and
"positions"?
if (nAssetPositions != nAssetPrices) {
cat("Different number of assets! \n\n")
<exit function>
}

barplot(names.arg) versus axis(labels)
Should I be able to use axis() on a barplot? i have a data.frame, the first
3 values of which are:

Setting where the x-axis crosses the y-axis
Hi all,
my apologies for a probably very obvious question but i can't figure out if, on
a bar plot, there is a simple way to have the x-axis cross the y-axis at 1,
when the y-axis is on a log-scale?
I want to draw a bar plot, and have some of the bars "drop" below 1 while
starting from 1. Is this possible?
I have been trying various things using barplot, barplot2 etc... without

Formatting of numbers on y axis
Hello all. I have the following:
plot(salaries$yearID, salaries$salary, type='n', xaxt='n', xlab='',
yaxt='n', ylab='')
axis(1, at=unique(salaries$yearID), labels=unique(salaries$yearID), lwd=.25,
tck=-0.05)
axis(2, axTicks(2), format(axTicks(2), scientific = F))
Which nicely creates the Y axis with the raw numbers, which are in the range
of .5 - 7

invert y-axis in barplot
Hi!
This is probably a very trivial question. Is there an easy way to invert the
y-axis (low values on top) when using the function barplot()?
Thanks,

How to adjust the y-axis range in barplot properly
Hello R-Users,
it might be a rather simple problem I have, but I couldn't find any
solution online. Thus, here is my problem:
I would like to adjust the y-axis range in a barplot, since all my
values are >70. Therefore I would like to only visualize the y-axis from
60-100 (example 1).
The problem is, the range of the y-axis is adjusted, but the barsize
stays the same and vanishes from

Barplot with "Independent" Lines Y axis
Hi list. I'm plotting pluviometric (Rain) data as a barplot, and then adding
the salinity variable to this plot as lines. Obviously as these Y scales are
completely different the salinity appears at the lower part of the graph
extremely compacted. I need to plot the line at the exactly same area of the
barplot but with its own Y axis (at the right), so the salinity can use the
plot area

barplot y axis too short
Hello,
The function barplot automatically creates a y-axis that doesn't necessarily
cover the range of y-values to be plotted. I know how to manually create my
own y-axis so that it does cover the range, but I was wondering if there is
some parameter to change so that the scale of the y-axis is automatically
taller than the tallest bar.
I thought setting xpd=F would do it, since it says that

changing format of y-axis (barplot)
Dear all,
I have some data.frame and I would like (1) change the format of y=axis to
escape of scientific format (like 1e+05...) and (2) label the value or other
variable on the top of the bar.
df<-data.frame(x=1:6,y=c(100,500,1000,25000,500000,1000000))
barplot(df$y,names.arg=df$x)

Using R to generate reports
Hi all,
I would like to generate nicely formatted reports on a daily basis. The
reports would be a combination of charts and tables, generated in an
environment such as R.
Ideally, this would be an automated process. Does anyone know if this is
feasible, and how I could achieve well formatted reports? One idea would be
to have R scripts process the data/generate the charts and then use

adding labels above bars in a barplot
Hello,
I want to make a general routine to draw barplots with numbers plotted
above each bar. See the example below.
I could not place the numbers on the middle of each bar because I
could not calculate the right position of each x-axis tick. axTicks(1)
indicated a unitary step, but it does not seem work.
I appreciate any help or suggestions.
Best regards,

Difficulty Replacing a Row of a Data Frame
I have the following data frames, avGain and retGain. They have the same
dimensions.
The following line of code replaces row j of avGain as desired:
avGain[j, ] <- mean( retGain[jStart:j, ] )
However, the following line does not work:
avGain[j, ] <- ( avGain[j-1, ] * ( DAYS - 1 ) + retGain[j, ] ) / DAYS
If I do the following, and test to see if a or b are data frames.

X and Y axis labels on a barplot
Dear all,
I have produced a barplot and wish to alter the axes a little. In place of the variable names appearing on the x-axis, I'd like to have the numbers 1986 to 1995. I have tried using the argument xlim=c(1986,1995) in the barplot command but receive: "Error in plot.window(xlim, ylim, log = log, ...) : invalid 'xlim' value"
Also, on the y-axis, the values are

pretty for a log-axis
Is there a function that does the same as pretty but on a log-scale?
Suppose you have
x <- exp( runif( 100, 0, 6 ) )
(which will between 1 and 403), then I would like to have a result like:
log.pretty( x )

Change the scale on a barplot's y axis
I have grades data. I read them from a csv in letter-grade format. I
then converted them to levels
levels(grades$grade)=c('A+','A','A-','B+','B','B-','C+','C','C-','D+','D','D-')
And then to numbers
grades$gp=grades$grade
levels(grades$gp)=c(4.3,4.0,3.7, 3.3,3.0,2.7, 2.3,2.0,1.7, 1.3,1.0,0.7)
