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

Dear list, I would like to plot arrows with different colors according to arrow length, and also (if possible) with head size proportional to arrow length. The idea is to make a quiver-like plot of matlab with wind speed data. So far, I´ve been able to use different colors, but I need to find a more efficient way to recode arrow length intervals into colors. On the contrary, I can't define

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,

Hi, I would like to convert my "character" sequences in my matrix/ data.frame into "numeric" where it is possible. I would also like to retain my alphabetic character strings in their original forms. "5.1" > 5.1 "hm" > "hm" k<-matrix(c("aa", "bb", 1,2, 4.3, 0), nrow=2) mode(k) <- "numeric" #

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

*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

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

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. Thanks in advance. Héctor Villalobos Windows XP, R 2.5.0 > bwplot(decrease ~ colpos |

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

We used samba 2.0.6 under Redhat 6.1 with W98/NT4 clients without any problems. Now we upgraded one PC with Windows2000. In the beginning everything worked fine. But suddenly there are problems: Browsing a specific subdirectory of a share on the server cause a inmediate crash of W2k with a automatic restart. I upgraded to Samba2.0.7, again W2k crashes. I connect to this subdirectory from a

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

Estimado Marcelino Hace mucho tiempo, no recuerdo cuanto, creo que casi todos encontramos en español dos artículos, uno de Argentina otro de Colombia, ambos en español, es lo que yo recuerdo, uno tenía el título de revista de bioingeniería, el otro de R para principiantes, o gráficos en R para principiantes, seguramente aún deben estar en el repositorio de R, documentación en español. Por lo

Has anyone had any luck with the paypal gem from leetsoft (Tobias Luetke)? I''m successfully sending off and making payments, but the ipn doesn''t send back to my site. I have the notify_url set in the form, have a action set for the ipn postbacks, but all I get from my sandbox after payment is a "view shops" page from paypal after payment is made. -- Posted via

I''ve got that working fine & test it actually works with cucumber (where I''ve turned CSRF back on, since it''s full-stack testing) but would like my controller spec to mention the need for protect_from_forgery :except => [:create] (and fail

Hi, I want to know how to use ntlm_auth with ntlm-server-1 and freeradius, with the users login and password information in ldap.

I have configured freeradius+ldap+802.1X for a wireless lan, but i

Estimados usarios de R: Tengo una base de datos madre en formato .sav de SPSS y la quiero modificar usando datos de otras base de datos .sav y otra en .csv a las que llamare hijos.
