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 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, 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, I have a model with differents observations Xi. Each observation belongs to a group, either A or B. I would like to minimize a fonction like : sum( Xi - Z)^2 + sum (Xi - aZ -b)^2 A B The first sum contains all observations from group A and the second all observations from group B. I want to find the Z-value wich minimize this function. a and b are predefined parameters.
