Dear R users: Sorry for this simple question: I am writing a function where I would need to pickup p values and make -log10 of it. The p values are from an anova output and sometime it can yield me 0. -log10 (0) [1] Inf I can not replace Inf with 0, which not case here. This is restricting me to go further in the function and out me the error. You help is highly appreciated. Thanks; --

Dear all, I would like to (i) produce boxplot graphs with axis in logarithm in base 10 and (ii) showing the values on the axis in 10^exponent format rather than 10E+exponent. To illustrate with an example, I have some widely spread data that I chart plot using boxplot() [figure on the left]; the log="y" option of boxplot() I obtained the natural logarithm conversion of the data and

Hi, I noticed the following bug while using R version 1.7.0 for Windows (and Linux): > floor(log10(1000)) [1] 2 > Here are my start-up messages: R : Copyright 2003, The R Development Core Team Version 1.7.0 (2003-04-16) R is free software and comes with ABSOLUTELY NO WARRANTY.

Is there a way to teach xy.coords, when given log="xy", or just "x" or "y" separately, to do a decimal log10 instead of the natural log? Cheers, Alexy

Dear help-list, I would like to perform a linear regression on the log10 of the two vectors ov.mag.min and res.600nm. The slope and intercept of the regression I use to plot a wider range of ov.mag.min in a double log plot. For a linear regression on only tow points, wouldn't I expect the results for two.points.min to match pretty exactly res.600nm? It does not seem to be the case here.

Hi, I have a histogram with values logged to the base 10 hist(log10(x),breaks=60) How do I show the log values on the x-axis and a second x-axis showing the real values? Thanks -- Shane [[alternative HTML version deleted]]

Can we expect to see an R package on Statistical Quality Control in the future like SPLUS? I can't understand why nobody made this package before. ______________________ Indrajit SenGupta Department Of Statistics St. Xavier's College Calcutta University indra_calisto at yahoo.com indrajitsg at vsnl.net ______________________ EC- 195 Salt Lake City, Sector -1 Calcutta 700064 West Bengal

Hello! I use Debian GNU/Linux at work and I really like apt-get tool. As far as I understand the whole picture, there are now some Debian packages of R packages. Build of Debian packages is done automagically by Perl script. By the way, what is the status of Debianizing R packages? Is it stopped, just holded, ... I don't know so I am asking There is also Bioconductor and I am aware that the

Hello. My name is Akashah. i work at metabolic laboratory. From my study, i found that volcano plot can help a lot in my section.  i already studied about the volcano plot and get the coding to run in R software, unfortunately, there is may be something wrong with the coding. This is because  no graph appear, but no error (blue color text) was shown on the R console. Below is the coding for

HELLO, anybody... could you help me to check the below coding for volcano. what is the mistake? what the plot could not display? # volcano_plot.r # # Author: Amsha Nahid, Jairus Bowne, Gerard Murray # Purpose: Produces a volcano plot # # Input: Data matrix as specified in Data-matrix-format.pdf # Output: Plots log2(fold change) vs log10(t-test P-value) # #

Dear all, I did a non-linear least square model fit y ~ a * x^b (a) > nls(y ~ a * x^b, start=list(a=1,b=1)) to obtain the coefficients a & b. I did the same with the linearized formula, including a linear model log(y) ~ log(a) + b * log(x) (b) > nls(log10(y) ~ log10(a) + b*log10(x), start=list(a=1,b=1)) (c) > lm(log10(y) ~ log10(x)) I expected coefficient b to be identical

Hi all, Suppose I want to set the values in a column to the log of the values of another column like so: object$LogDist <- log10(object$Distance) How do I loop through the objects if I have object1, object2, etc to perform this function? object1$LogDist <- log10(object1$Distance) object2$LogDist <- log10(object2$Distance) object3$LogDist <- log10(object3$Distance) I was trying to

Hi all, I would like to test the homoegeneity of variances between several linear model for some analysis of covariance. It seems that the Bartlett's test is a good test to use but I am having problem using with linear model and I cannot find any examples on the internet. There are some examples for comparisons of variances but not linear models. If I take the hellung data set, which is

Hi, The default value for lag.max in ACF implementation is 10*log10(N) There several publications recommending setting lag.max to: - N/4 (Box and Jenkins, 1970; Chatfield, 1975; Anderson, 1976; Pankratz, 1983; Davis, 1986; etc.) - sqrt(N)+10 (Cryer, 1986) - 20<=N<=40 (Brockwell and Davis) Why R uses 10*log10(N) as a default? Please, give me a reference to a book or article where the
