Linking 2 columns in 2 databases and applying a function
Hi all,
I have two datasets, one that represents a long-term time series and one
that represents summary data for the time series. It looks something like
this:
x<-data.frame(Year=c(2001,2001,2001,2001,2001,2001,2002,2002,2002,2002,2002,2002),
Month=c(1,1,1,2,2,2),Q=c(5,5,5,6,6,6,3,3,3,4,4,5))
y<-data.frame(Year=c(2001,2001,2002,2002),Month=c(1,2,1,2),Threshold_Q=c(5,5,4,4))

Finding/identifying a value within a factor
Hi all,
I'm trying to identify a particular digit or value within a vector of
factors. Specifically, this is environmental data where in some cases the
minimum value reported is "<" a particular number (and I want to manipulate
only these). For example:
x<-c("1","2","3","4","<1")

Boxplot of multiple vectors with different lengths
Hello,
I'm attempting to write a code that automatically imports data from
different files (with different lengths-just one variable) and makes tidy
box plots for comparison. I can successfully import the data and create a
list of the vectors I want to compare. But I cannot, for the life of me,
figure out how to generate box plots using the "list" option. Suppose these
are my data:

Counting number of rows with two criteria in dataframe
Hi R-users,
I'm trying to find an elegant way to count the number of rows in a dataframe
with a unique combination of 2 values in the dataframe. My data is
specifically one column with a year, one with a month, and one with a day.
I'm trying to count the number of days in each year/month combination. But
for simplicity's sake, the following dataset will do:

Deleting rows with NA from isolated column in matrix
Hi all,
I'm relatively new to R and have a data management problem. I am importing a
data matrix with some columns that have missing values. I am trying to
figure out how to delete rows with NA for data FOR JUST ONE SPECIFIED
column. For instance, with the example matrix:
x<-matrix(nrow=5,ncol=3)
x[,]<-1
x[5,1]<-NA
x[3,3]<-NA
how do I tell R to delete any rows with an NA value

Different gridlines per panel in xyplot
In the example R script below, horizontal gray gridlines are drawn at y
coordinates where the points are drawn with the code:
panel.abline(h=y, v=xScale, col.line="gray")
How do I change this so that the horizontal gray gridlines are drawn at y
coordinates where the y labels are drawn? The challenge is that each panel
has different y-ranges (in my real example the y-ranges and

Hmisc and Lattice question on gridlines
I have been using lattice xyplot and am quite pleased, and I can use the
type=c("b","g") to have it print gridlines into the page, yet if I want to
have a line plot with points on it, how do I get the xYplot to print
gridlines (I use Hmisc xYplot because of its bands method which allows
plotting of confidence intervals). Any suggestions? I have looked at the
panel functions but

Question about barplot: gridlines & value labels
Hello!
I promise I looked into help files before asking. Still cannot figure
it out. I think it's because I am totally confused what packages use
lettice, which use trellis, etc.
Sections 1 and 2 below produce the data and the data to plot. My
question is about barplot in Section 3. I am trying to:
1. add only horizontal gridlines and manipulate the type and color of
that line. tck = 1 is not

abline by groups
Hello,
I have 2 variables - x and y, that belong to separate groups.
I want to plot all the x and y together, but show separate abline for each
group. It can be done in ggplot2, but is there a simpler way to draw
ablines by group?
e.g.,
mydata <- data.frame(x = 1:20+rnorm(20, -3, 1), y = seq(1,20,by=1), group =
rep(letters[1:5],20))
plot(x,y,col=mydata$group) # need to get separate ablines

tics and grids
Hi,
Whats the easiest way to set a desired interval for tics on axes in R ?
And will the 'grid' command put gridlines on all tics automatically ?
I tend to get stuck with graphs with ranges 0-1 with only 2 tics and 2
gridlines in the 0-1 range, while I would like 10 tics (or every 0.1)
tnx,
Piet

Subject: Removing lattice graph gridlines and editing label box colour
Hi,
Is it possible to remove the background gridlines from a lattice graph (ie graph made up of multiple individual graphs with annoying blue grid in the backgroun)?
Also, Is it possible to change the colour of the individual graph label boxes? - ie the default pink boxes above the individual graphs

figure margins too large for a barplot in png, pdf ok

change colour of geom_step by scale_colour_manual
Hi,
Color of my step plot is now by default. Now I'd like to change the color as
the grey scale I specified. I don't know why I got three black plot. Here I
attach two version of codes. The first one produces a step plot with color
by default. The second one, modified from the first one, is not producing
the grey scale I want. Any help would be highly appreciated.
