[R] Loading data into R
Hello again, I generally use Clipboard to load data into R from Excel using the read.delim() function. In most cases, my data after loading looks like below: myData - structure(list(V1 = structure(c(3L, 2L, 1L, 1L, 2L), .Label = c(, 2, a), class = factor), V2 = structure(c(4L, 3L, 1L, 2L, 1L), .Label = c(, 34, 4, b), class = factor), V3 = structure(c(3L, 1L, 1L, 1L, 2L), .Label = c(, 4, c), class = factor), V4 = structure(c(3L, 1L, 1L, 2L, 1L), .Label = c(, 4, d), class = factor), V5 = structure(c(4L, 3L, 1L, 1L, 2L), .Label = c(, 4, 7, f), class = factor)), .Names = c(V1, V2, V3, V4, V5), class = data.frame, row.names = c(NA, -5L)) myData V1 V2 V3 V4 V5 1 a b c d f 2 2 47 3 434 4 5 2 4 4 Now I want to put this data in a Matrix class with all elements are character. So tried this : as.character(myData) [1] c(3, 2, 1, 1, 2) c(4, 3, 1, 2, 1) c(3, 1, 1, 1, 2) c(3, 1, 1, 2, 1) c(4, 3, 1, 1, 2) This looks funny and does not conform the original data. Can somebody point me what would be right way to put it into Matrix?

Re: [R] Loading Data to R
On Microsoft Windows systems, it may be more convenient to install and use the XLSReadWRite packge. For non-windows systems, the gdata package provides this function, but requires perl to be present. -Greg (Maintainer of gdata) On Feb 9, 2008, at 1:09PM , Henrique Dallazuanna wrote: You need library(gdata) before On 08/02/2008, Wensui Liu [EMAIL PROTECTED] wrote: # READ DATA FROM XLS FILE # xls - read.xls(file = C:/projects/Rintro/Part01/export.xls, sheet = 3, type = data.frame, from = 1, colNames = TRUE) On Feb 8, 2008 3:49 PM, Christine Lynn [EMAIL PROTECTED] wrote: This is the most basic question ever...I haven't used R in a couple years since college so I forget and haven't been able to find what I'm looking for in any of the manuals.

Re: [R] Loading Data to R
Have a look at the R Data Import/Export manual on the R website. My simple-minded approach is simply to save the data as a csv file and read it in using read.table or read.csv --- Christine Lynn [EMAIL PROTECTED] wrote: This is the most basic question ever...I haven't used R in a couple years since college so I forget and haven't been able to find what I'm looking for in any of the manuals.
