similar to: ylab in time series plot (PR#2869)

I am using R-1.7.0 and have some data which consist of one vector of numbers and a second corresponding vector of dates belonging to the POSIXct class. I would like to plot the numbers against the dates. What is the best way to do this? It almost works to just call `plot.' However if I do this while using the `ylab' parameter I get a warning message: parameter "ylab"

Would it be hard to make the X11 device driver in R accept general X11 resources? In particular I would like to be able to set the title of the graphics window when I start it up. (Note this is not the same thing as the title of a plot but rather is the character string visible to the window manager, and usually goes in a titlebar on top.) For example in Splus one can do > motif('-xrm

The initial authors of R said?, "...we implemented the language by first writing an interpreter for a Scheme subset and then progressively mutating it to resemble S." Further on in that article they elaborated that their strategy was to create a parser that would take expressions in S-like syntax and translate them to Scheme S-expressions. Does R still work that way? Can R be made to

Although the documentation is somewhat sketchy, I() can be used to create objects of class AsIs: > I("a") [1] "a" attr(,"class") [1] "AsIs" "character" > I(4) [1] 4 attr(,"class") [1] "AsIs" "numeric" > I(4 + 0i) [1] 4+0i attr(,"class") [1] "AsIs" "complex" > This

Hi, In 1.4.1, I was able to create extra "empty" rows in a dataframe as so: > x <- data.frame(a = letters[1:3], b = 1:3) > x a b 1 a 1 2 b 2 3 c 3 > x[4,] a b NA NA NA > rbind(x, x[4,]) a b 1 a 1 2 b 2 3 c 3 NA NA NA > R.version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

I don't seem to be able to initialize a vector of NAs. I hope this is a bug and not a new feature (I realize I have not paid much attention to a lot of recent discussion about NA): platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1 minor 5.0 year

Hello List, Knowing I would eventually need to ask for help on the list, I've held off my thanks and congratulations on the 1.+ releases of R. I am amazed at the dedication of the R-core team, and do add my applause and thanks. I've had a compile problem with the latest version which has not occurred before. I'm compiling under: platform sparc-sun-solaris2.6 arch sparc

I was surprised not to find dev.ask when I looked for it. Is there an alternative method of holding plots before going on to the next one? > R.version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1 minor 1.1 year

Typically, when I use strptime with "impossible" dates I get an NA, which is what I expect. > version _ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1 minor 3.0 year 2001 month 06

Hello everybody, if I'm using par(xpd=NA) gridlines will plotted outside the plotting region. This is "new" (and, in my opinion, unaesthetic) in version 1.4 - compared to version 1.3. Is this a bug or a feature? Example: ------------------ par(xpd=NA) plot(1:11) grid() ------------------ platform sparc-sun-solaris2.6 arch sparc os solaris2.6

Hi, I think that there is something that I am misunderstanding in creating tables using dates that are of class POSIXct. Consider: > x <- data.frame(date = as.POSIXct(strptime(c(rep("2002-10-17", 4), rep("1999-12-08", 2)), format = "%Y-%m-%d"))) > x date 1 2002-10-17 2 2002-10-17 3 2002-10-17 4 2002-10-17 5 1999-12-08 6 1999-12-08 > table(x$date)

R> order(1, na.last=NA) Error in apply(sapply(z, is.na), 1, any) : dim(X) must have a positive length This bug appears unrelated to PR#1906, and so the fix of 8/15 doesn't help. It comes from the line inside order(): ok <- !apply(sapply(z, is.na), 1, any) where z=list(1) in my example. sapply() returns a single-element vector, not a matrix, making apply() unhappy. This might

Here's a simple example: > x <- rnorm(20) > y <- 1 + 10*x + rnorm(20) > plot(y ~ x, subset=2*(1:10),xlab="In",ylab="Out") Error in length(x) == l : comparison (1) is possible only for vector types The problem seems to be in this section of the code for plot.formula: if (!missing(subset)) { s <- eval(m$subset, data, parent.frame()) l

I often use merge with dataframes that contain character vectors which have elements that are sometimes "NA" (meaning the string NA, not the same thing, obviously, as NA in a numeric or factor vector). For example, the stock ticker for Nabisco was "NA". Unfortunately (for me), it seems like merge insists on inserting "NA" for missing values. My question: Is there some

Seems to be a day for finding peculiar little things. There is an inconsistency in the behavior of lm vis a vis glm: > x <- rnorm(15) > y <- 1 + 10*x + rnorm(15) > z <- as.factor(rep(c("A","B","C"),rep(5,3))) > xyz <- data.frame(x,y,z) > fit.lm <- lm(y ~ x + z, data=xyz, subset=(z != "C")) > fit.glm <- glm(y ~ x +
