geom_text overlapping text and alignment of text in ggplot2

I have to draw table like look through geom_text() and i have tried using position_jitter /dodge and hjust to make it look like a table and to change text being overlapped or arranged in a oblique manner.

Here is a sample code :

require(ggplot2)
require(reshape2)

dia3 <- melt(CO2, id = c(colnames(CO2)[1],colnames(CO2)[2]))
dia3

p <- ggplot(dia3, aes_string(x=colnames(dia3)[2],y=colnames(dia3)[1],color = colnames(dia3)[3]))+
  geom_text(aes_string(label = colnames(dia3)[4]),
           position=position_dodge(width = 0.5),
            hjust = 0.5,
            size = 2.5
  )+
  scale_x_discrete(drop = TRUE)+
  theme_bw()+
  theme(
    axis.ticks.x = element_blank(),
    axis.text.y= element_text(color="black", size=8),
    axis.title.y = element_blank(),
    axis.title.x = element_blank(),
    legend.key = element_rect(fill="white"), legend.background = element_rect(fill=NA),
    legend.position="bottom",
    legend.title = element_blank(),
    panel.grid  = element_blank(),
    panel.border = element_blank()
  )
p

It produces plot like : enter image description here

I need help with arranging all the text aligned in vertically straight lines.

Thanks

The dodging is done by group, which is automatically set to any factor variables you have mapped, which includes x in this case. Override the default to fix the problem:

ggplot(dia3, aes_string(x = colnames(dia3)[2], y = colnames(dia3)[1], 
                        color = colnames(dia3)[3], group = colnames(dia3)[3]))+
    geom_text(aes_string(label = colnames(dia3)[4]),
              hjust = 0.5,
              size = 2.5,
              position = position_dodge(0.5)) +
    scale_x_discrete(drop = TRUE)
