Hi, I need your help!! I imported a big coloumn vector from a txt file but it results as mode :"list" I want to change it in numeric otherwise I can't do my analysis. This is what i get: mode (data) <- "double" Error in eval(expr, envir, enclos) : (list) object cannot be coerced to type 'double' > Thanks a lot!!! Alessandra -- View this message in

I'm looking for a function that lists a few summary stats for a column (or row) of data. I'm aware of summary(x), but that does not give me what I'm looking for. I'm actually looking for something that is very similar to the descriptive statistics tool in excel; i.e. Mean, Std. Error, Std. Deviation, Kurtosis. I'm positive that I came across a function that did this (possibly

Dear readers of the list, I have a problem a comparison of two data from a vector. The comparison yields FALSE but should be TRUE. I have checked for mode(), length() and attributes(). See the following code (R2.10.0): ----------------------------------------------- # data vector of 66 double data X =

Hi, Can anyone please tell me if I am right in assuming that ext3 does not care about file slack? Specifically I am thinking about the use of the secure_delete utility which, includes "sfill" to do secure overwriting of the unused diskspace on the harddisk. I quote from the secure_delete README below for its modus operandi (I appreciate that some of this will not apply to sfill).

``We all know'' that R has more flexible and nicer color specifications than S-plus. There are situations however, where I'd like to specify colors numerically, e.g. 1) convenience of using different colors in a for(.) loop or 2) backward compatibility with S. In S, there's the quite known ``standard'' col = 0 :<==> current background color [ = white by

Dear useRs, I have a longitudinal experiment with several treatment groups, ~20 subjects per group, ~6 timepoints and a continuous dependent variable. I have been successfully been using lattice::xyplot with this data. However, I have been stumped with a particular application of it. I would like to use xyplot on my data, broken into treatment groups with the groups argument, using

Hi All I am looking for a way to prefix a constant value to all the rows in column in a data frame. Eg. V1 2 3 4 5 I want to make it like this V1 number2 number3 number4 number5 Thanks! -Abhi [[alternative HTML version deleted]]

Hello Gurus, I am still new to R. Here is my issue. I was trying to add column to data frame that was populated by read.spss(). When I used cbind to add a new variable(column). library(foreign) mydf<-read.spss(file="C:/myspss.sav",use.value.labels=FALSE, to.data.frame=TRUE,use.missings=FALSE) attr(mydf,"variable.labels") ## it gives you all the labels

Dear R-helpers, x <- rep(1:2, 4) y <- c(2, 4, 3, 5, 1, 3, 2, 4) w <- factor(rep(1:2, each = 4)) v <- rep(1:2, each = 2, 2) xyplot(y ~ x | w, groups = v, type = 'b') How do I tell xyplot to use four colors and four plot characters and four line types? And how do I set up an appropriate key in each? _____________________________ Professor Michael Kubovy University of Virginia

Hi guys. The 'col'-parameter in the 'hist'-method for the classes 'POSIXt' and 'date' does not perform as it does in the default 'hist'-method. Unfortunately, it does not only change the filling color of the boxes, but also the color of the axislines. [Using 'graphics'-package version 2.2.0] Examples: # with POSIXct-object hist(.leap.seconds,

I have a very short question. Is there any possibility to give to the parameter "col.axis" of graphics function "axis" a vector value of many colors instead of just one color, otherwise is there any way around it? Thank you very much Enio Jelihovschi UESC - Brazil [[alternative HTML version deleted]]

Hi, I am trying to color the data points on my boxplot but I only get the default black. Not sure why. Any ideas? Thank you, Mark Here is my code. > dat.g100 <- dat.sg[100,] # selected gene (row) from a dataframe of 37 columns > d1 <- as.matrix(dat.g100[,1:18]) # subset 1 > d2 <- as.matrix(dat.g100[,19:37]) # subset 2 # boxplots > par(mfrow=c(2,1)) > boxplot(d1,

Hi list, My data set is comprised of 47 columns and about 700 rows. Most of the values would be around 2, while some will go beyond in either direction, higher or lower. Is there a way to specify the parameter of col or others if necessary to have the range of representing colors be 0----8, and make dark for 2, red for higher than 2 and green for lower than 2. Is there a way to do this? Thanks a

Ok, simple case. MySQL table with date column. The date column default is 0000-00-00. When I view these rows in say SQLyog, all rows in this table have value of 0000-00-00. by default. ..... Now, onto my Rails app. I don''t even care about the date column described above. I am attempting to update an entirely different column in the same table. However, when I use an active record to

I am trying to run, in R -Windows95, the example in MASS2, section 17.2.

Is there an easy way to use library on VR in general or do I have to move each into
