similar to: lda function

Hi, I'm writing for a little help. I have a dataframe with same NA value and I'd like to obtain the means of the value of a coloumn grouped by the levels of a factor coloumn of the datframe. I'm using the function "tapply" but I see that if only a NA value is present the result is NA. There is an option to have the correct result or I must use an other function? Thanks of

Hi, I'd like plot a bar graphic of a array. I'd like to have the values of the single columns as juxtaposed bars (like in "barplot" with beside=TRUE) and I'd like to have the values of the single columns expressed like percentage of the sum of the coloumn. In this way all the bars are composed by the sum of the percentage of the values of a coloumn (with different colors)

Hi list, I'm looking about lda function. I'd like to know how calcolate the value of the discriminant functions for the original datas. I see that in the result object "lda" there is $scaling a matrix which transforms observations to discriminant functions, normalized so that within groups covariance matrix is spherical. I'd like to have the value of the discriminant

Hi all, I have a simple question: I have a data.frame like this: id x y 1 50 1647685 4815259 2 50 1647546 4815196 3 50 1647454 4815294 4 50 1647405 4815347 5 50 1647292 4815552 6 50 1647737 4815410 7 74 1647555 4815201 8 74 1647464 4815023 9 74 1646970 4815129 10 74 1646895 4815264 11 74 1646762 4815513 and I'd like to trasform it with the "convert.to.shapefile"

Hi all, I have a little problem selecting some rows from a data.frame. I'd like to select the rows where a determinated column take a partivolar value.

Hi all, after moving to parametrized classes, I''ve started to declare them instead of including. Now, I''m trying to understand the differences (internal) between declare and include, and, reading http://docs.puppetlabs.com/guides/parameterized_classes.html again, I found some sentence which confuses me: "Since include wasn’t designed for use with parameterized

I used to use Wine (from 0.9.x to 1.1.x) on ArchLinux 32 bits to run a Brazilian Dictionary called Houaiss [1], and it worked almost flawlessly. But then I got a new computer and installed Ubuntu 64 bits on it, and now Houaiss' interface is unreadable (same Windows software, not a 64 bits version). I'll provide further information below, and I'd like to know if it's a 64 bits

Hello all, I'm having the following problem. I have a Win95 PC in a WAN, and a Linux WINS. For the local subnets there's no problem, but the WINS seems to react very slowly for the WAN pc. - both WINS and win95 have the same workgroup; the workgroup is not in any computer name (as far as I know and can see) - ICMP echo about a 35 msec reply tcpdump shows a couple of 137 < - > 137
