In the following example: x <- rnorm(1:100) y <- seq(from=-2.5, to=3.5, by=0.5) z <- as.matrix(table(cut(x,c(-Inf, y, +Inf)))) ## I wish to transform the values in z j <- log(z) ## Yet retain the row names row.names(j)<-row.names(z)
Hmm. The rownames were retained and row.names() is for data frames, rownames() for matrices.
Now, how can I go about creating a scatterplot with row.names(j) on the x-axis and j(m:nrow(j)) on the y-axis? Keep in mind the transformation I am conducting is more complicated and therefore cannot be plotted directly using log(z), which places me in this unique position.
You will need to explain what exactly you want plotted. A scatterplot is of two continuous variables and you only have one (and 'j(m:nrow(j))' is invaild R). But here is one possibility to get you started:
m <- nrow(j) plot(j, xaxt="n", xlab="") axis(1, 1:m, rownames(j), las=2)
