barplot and map overlay
Hi, I wonder if it is possible with the graphics package to overlay one or several plots (barplots, for example) over a map. Data for the map is in a data frame with the latitude and longitude coordinates, and then: > plot(map$long, map$lat, type ="l") produces the map. I want to put each barplot in specific locations on the map, namely at the center of "statistical

coping with a warning in if()
Hi, I'm sure this one is very easy.... I am trying to write a function where one of its arguments has two posible (strings) values, defaulting to one of them if none is specified. My problem is that when evaluating the function the following warning is produced: "the condition has length > 1 and only the first element will be used" I've read the help page of if() but I

manipulating text to generate different formulas to use in nls()
Hello, In doing a series of non-linear estimations of a function which is a sum of a varying number of sinusoids, I would like to "autogenerate" the arguments needed by nls() depending on that number. For example, when there are two sinusoids: > nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data, start = list( mu=some.value0,

Reading biplot function's source code
Hi everybody, Excuse me for this silly question, but after searching the help archives I'm still unable to find my way to read the source code of the "biplot" function in R. I have installed the mvbutils package, and tried: > fixr(biplot) which only gives me: function (x, ...) UseMethod("biplot") with no further details.... I'd like to read the code to see if

zero center a group of variables
*This message was transferred with a trial version of CommuniGate(tm) Pro* A simple question, perhaps to simple, but I am new to R: For a data frame with k variables and n1+n2 observations (two groups) how can i substract the group means for every variable, so both group variables become centered to mean zero? Thanks in advance for your help H?ctor

retrieving stats from bwplot
Hi all, I want to retrieve the stats from a 'bwplot' with one factor. I have read the help for 'panel' function and I'm aware of the option 'stats' which defaults to 'boxplot.stats' but I didn't understand it well and therefore I am unable to get what I need.

axis labels in multiple plots
Hi, I'am trying to make a multiple bar plot over a map and I'm having difficulties with the distance between axes labels and the axis. Trying to control this with mgp does not help because it controls both axes simultaneously. For example, with default values (mgp = c(3, 1, 0)) y-axis labels are ok, but x-axis labels are not. Setting mgp = c(3, 0, 0) gives good x-axis labels but the

how to use ntlm_auth

I discovered that lld for darwin is generating the wrong code for lazy bindings in the __stub_helper section (at least for osx 10.12). This is the way i can reproduce this problem, using this program: program: #include <stdio.h> int main(int argc, char **argv) { printf("C: printf!\n"); puts("C: puts!\n"); return 0; } Then I link it using i have tested it

Hi, I'm having difficulty to replicate in R a nested (hierarchical) anova example found in p. 308 of Zar, J.H. 1996. Bostatistical Analysis. Prentice Hall. 3rd ed. The example (15.1) is as follows: The variable is blood cholesterol concentration in women (in mg/100 ml of plasma). This variable was measured after the administration of one of three different drugs, each drug having been

nls() vs lm() estimates
Hi, I'm trying to understand why the coefficients "a" and "b" for the model: W = a*L^b estimated via nls() differs from those obtained for the log transformed model: log(W) = log(a) + b*log(L) estimated via lm(). Also, if I didn't make a mistake, R-squared suggests a "better" adjustment for the model using coefficients estimated by lm() . Perhaps I'm
