similar to: Mike Meyers A+ CD with wine

I have the CompTIA A+ course on cd, It opens the first menu but is stuck there. The accept/decline window opens with the EULA but I can't scroll up or down or hit accept. Has anyone else used these CDs with Wine successfully?

Rers: I have some ecological data (stream velocity vs. % cover of submerged weeds) that shows strong evidence of a thresholding step-function, e.g. below some velocity, % cover ranges from 0% to 100% (with no apparent relationship to velocity within this range of velocities), but above a certain "threshold" velocity, the % cover does not appear to exceed, say, 10%. There are good

Hello. I've just started using R and am trying to figure out if the two codes snippets below have the same output gBest<-floor(runif(popsize,min=1,max=top)) velocity[i,j]<<-.4* velocity[i,j] + 1 * runif(1) * (pbestsVar[i,j] - popVar[i,j]) + 1 * runif(1) * (archiveVar[gBest,j] - popVar[i,j]) and for (i in 1:popsize) { for (j in 1:maxvar) { gBest<-sample(top,size=1)

Hello, does anyone knows this predict is not resulting? # lm predict dfTestes3sitesCriptic$Velocity_corrected <- ifelse (dfTestes3sitesCriptic$Season == "A" & dfTestes3sitesCriptic$BeforeAfter == "Before", (dfTestes3sitesCriptic$Velocity * mVel3ABefAfter), (ifelse (dfTestes3sitesCriptic$Season == "Sp" & dfTestes3sitesCriptic$BeforeAfter ==

I have constructed a Trellis style xyplot. lengthf <- factor(length) xyplot(SLI$velocity ~ SLI$width | SLI$lengthf, layout = c(2,7), xlab = "Width (cm)", ylab = "Velocity (m/s^2)", col = "black") This produces a lovely little plot. However, the grouping factor(lengthf) isn't in the right order. My values range from 2-28 and the 2 graph on the bottom left and

Dear all, I have the following output generated by linear regression. Since there is only one regression intercept and one slope for one set of data, what is the meaning of std. error for intercept and that of slope? Thanks in advance. Sincerely, Minghua > data(thuesen) > attach(thuesen) > lm(short.velocity~blood.glucose) Call: lm(formula = short.velocity ~ blood.glucose)

Dear helpers I have two data sets saved as vectors (temperature and velocity). Now I need to "take out" a span of temperature and its corresponding velocity in the other vector. How can I achieve that? I tried to write a function,which takes a vector entry and then decides wether to delete the temperature entry or not and simultaneously doing so with same entry in the velocity

Hello All, I'm trying to print specific row and column for Observed_Scores matrix, however, when I execute the command "Observed_Scores[1,1]", I get the message "Error in Observed_Scores[1, 1] : incorrect number of dimensions". Could you please help and let me know where is the mistake? Here is my program: library(ltm) library(psych) # Settting the working directory

I have installed Sweave as recommended. http://lifeasclay.wordpress.com/tag/sweave/. Placing a test.Rnw file, for instance, in "/Library/Frameworks/R.framework/Versions/2.15/Resources/library/utils/Sweave" generates test.tex files that generate pdf files with LaTeX. To be honest, placing Rnw files seem to make sense. The "exams" package does require not this step. It uses

Dear All, I am getting some data from fluid dynamics simulations (air mixing in a pipe, 2D axial symmetry, geometry described by a radial coordinate r and an axial coordinate z) which I'd like to plot and analyze with R. Think about slicing the cylinder along its axial direction to get a set of cross sections which are orthogonal to the z axis. For each section, I have a set of velocity

Hello, We are having some strange issues with RODBC related to integer columns. Whenever we do a sql query the data in a integer column is 150 actual data points then 150 0's then 150 actual data points then 150 0's. However, our database actually has numbers where the 0's are filled in. Furthermore, other datatypes do not have this problem: double and varchar are correct and do not

Dear useRs, the new R package exams provides Sweave-based automatic generation of exams with multiple-choice questions and arithmetic problems. The package is available from CRAN: http://CRAN.R-project.org/package=exams It includes a vignette giving an overview of the main design aims and principles as well as strategies for adaptation and extension. Hands-on illustrations - based on example

I am have tried the following: plot(x,y,xlab=expression(paste("Target Velocity (",ms^-1,")")),ylab="Passage Probability",ylim=c(0,1)) which works fine. I tried changing to:

Hi All, I'm generating 10 different data sets with 1 and 0 in a matrix form and writing the output in separate files. Now I need to stack all these data sets in one vector and I know that stack only operates on list or data frame however I got these data sets by converting list to a matrix so can't go backwards now. Is there a way i can still use Stack? Please see the program:

Dear R Users, I've never used R before and my professor has asked us to do some pretty intense programming (or it's intense to me at least). Here is the question: Modify the function myquadrature inside the script so that it returns the quadrature of descrete data using the trapezoidal rule. Modify the call to the function at the bottom of the script so that is uses your modifies

Hi list, I have a shorewall installed on 2 interfaces which also has multiple static public IP. Let''s say I have 1.2.3.4 and 1.2.3.5. I have assigned nat with: 1.2.3.4 eth0 11.22.33.4 no no But then I have a situation where I need 11.22.33.44 to connect to a host in the net zone and appears also to be 1.2.3.5 not only 1.2.3.4. How to do it? TIA Willy
