Is there any simple way to do this (e.g. some function that tests if a vector is coercible to a numeric before doing so)? --j -- Jonathan A.

...- glm(value ~ ., data=crs$dataset[,c(1:59,922)], family=binomial(link="logit")) I am not clear about what value ~ . means and also, I see data=crs$dataset[,c(1:59,922)] I have read that the data argument is optional here "an optional data frame, list or environment (or object coercible by as.data.frame to a data frame) containing the variables in the model. If not found in data, the variables are taken from environment(formula), typically the environment from which glm is called" when they say "data", is that meant to include the dependent variable as well.

Hi, I would like to get lapply() to work in the natural way on a class I've defined. As far as I can tell, lapply() needs the class to be coercible to a list. Even after I define as.list() and as.vector(x, mode="list") methods, though, I still get an "Error in as.vector(x, "list") : cannot coerce to vector". What am I doing wrong? # dummy class setClass("test", representation(test="list")) #...

...ouple of data sets which create errors and halt the loop. One of the tables looks like the following: dbh Black Walnut 1 8 38.19722 2 10 48.89244 3 12 38.19722 When the loop attempts the barplot() function, the following error is returned: Error in seq_len(p) : argument must be coercible to non-negative integer In other cases, there is simply no data in the specified set of data. Therefore, the table is full of NA's. Obviously, this does not need to be plotted, but I cannot simply remove it from the larger database. I need my loop to continue regardless of if it runs into the...

While browsing some code I discovered a call to lm that used a formula y ~ X - 1, where X was a matrix. Looking through the documentation of formula, lm, model.matrix and maybe some others I couldn't find this useage (R 2.10.1). Is it anything I can count on in future versions? Is there documentation I've overlooked? For the curious: model.frame on the above equation returns a

...levels of `y` are contained in `x`. So to find the common type of two factors, we take the union of the levels of each factor, given a factor that has finer resolution than both. Finally, you can think of a character vector as a factor with every possible level, so factors and character vectors are coercible.

Hi there, In the following example, sd() can be applied to a character vector. However, mean() can not be run in a similar way. Why? I have read sd() man page, however, I don't find information about that behavior. > x <- as.character(1:10) > sd(x) [1] 3.02765 > mean(x) [1] NA Warning message: In mean.default(x) : argument is not numeric or logical: returning NA Regards,

I've been working with raw vectors quite a bit and was wondering if the R team might comment on where they see raw vector support going in the long run. Is the intent that 'raw' will eventually become a first class data type on the same level as 'integer'? Or should 'raw' have more limited support, by design? For example, with very minor changes to subassign.c to

Dear all I am trying to represent a dependent variable (treatment) against different independent variables (v1, v2, v3....v20). I am using the following command: boxplot(v1~treatment,data=y, main="xxxxxx",xlab="xxxxxx", ylab="xxxxxx") However, it provides me only one graph for v1~treatment. For the other comparisons, I have to repeat the same command but changing

...lot when run from the command line is that Jeff went to the trouble to make it do that. addTA is not intended to add a plot to an existing chart. Yet the problem I ran into is that the addTA documentation doesn't say that. Instead it says, "addTA takes a series of values, either in a form coercible to xts or of the same length as the charted series has rows, and displays the results in either a new TA sub-window, or over/underlayed on the main price chart." I took that to mean that when I called addTA (from anywhere) a plot would be added to an existing plot. But that's not true....
