...minimum of entries of a numeric vector, without using loops or user defined functions. Suppose we have a vector: a <- c(3,1,2) then, min(a) = 1 and its index is 2. Target: how to get the index of this minimum? How to get the indices if multiple entries assume this same minimum? Thank you, Chee [[alternative HTML version deleted]]

Hallo to everybody out there, I have downloaded and compiled Samba3b2 on a SuSE 8.2 machine. For testing purpose, I connect to this machine with a Win2k-Box ... most things seem to work fine, but I am unable so change passwords from the win-box with unix password sync enanbled. I changed loglevel to 103 and enabled password chat debug. From what I found in the log-files, I can conclude that

...ith-tk-config=/usr/sfw/lib/tkConfig.sh --without-blas The "make check" ran without a problem after this. I hope that the sun compiler people can look into this and see if there is a problem with the sunperf library. Maybe Peter Dalgaard ha further insights into this? Thanks.

...z, such that: given values for x,y, f(x,y,z) is still a function of z and that I am still allowed to find the root in terms of z when x,y are given. For example: f(x,y,z) = x+y + (x^2-z), given x=1,y=3, f(1,3,z)= 1+3+1-z is a function of z, and then I can use R to find the root z=5. Thank you. -Chee [[alternative HTML version deleted]]

Dear All, I would like to generate m positive real numbers c_i, I=1,...,m, such that (1) c_1 + c_2 + ... + c_m=m, (1) after being ordered into c_1 >= c_2 >= .... >=c_m>0, we have that c_m is of the same order of m^(-1/8), when m is sufficiently large.

...4], ie, the original index of csort[2] is 4. When length(c) is very large, manual checking is infeasible. We can set up a for loop to compare and extract the index. However, is there an easier way to do this, so that the output is the sorted vector and their corresponding original indices. Thanks Chee [[alternative HTML version deleted]]

...a 4-by-4 plot by xyplot, i.e., 4 sample size values, each of which has 4 plots. I know how to do this using plot, but the spaces between subplots are big. I do not know how to make each subplot in xyplot an overlayed one as it would appear using plot. Any help would be appreciated! Thank you, Chee [[alternative HTML version deleted]]

In this case, max_indx = 4, since the 4th entry of A is such. Could you please give me some hints? Thank you, -Chee [[alternative HTML version deleted]]

Dear All, In Storey's estimator of the proportion of true nulls, the estimator depends on the tuning parameter lamda. Suppose now that an estimator of this proportion has been obtained by the qvalue package, what is the lamda that corresponds to the estimate? How to get this lamda? Thanks, -Chee [[alternative HTML version deleted]]

...Now suppose these m random variables are jointly m-dimensional normal with correlation matrix M= (m_ij). How to proceed next or how to start correctly ? Question: 1.

But I wan5 them to be 0, .5, 1, since the former way uses limited space of a multi-subgrap plot by adding extra zeros Thank you, Chee [[alternative HTML version deleted]]

Hi, I am currently trying to move my rubyonrails app from Linux to Windows server utilizing MS SQL instead of MySQL due to "business" reason. All my listing screen utilize a drop down list in each column to allow user to "filter" the listing based upon the value chosen from the drop down list. In the controller, I used find() method but with customized parameters such as
