ggplot2

问题 Might be missing something simple here, but my goal is to plot two heatmaps from two separate matrices. The matrices are of different dimensions, but I want each of the individual plotted tiles to be the same physical measurements between the two graphs. The graph size should then be dependent on the matrix dimensions, since the tile size will be constant between the graphs. Here is an example of two different size matrices and a stripped down version of the graphs I want to make. mat_lg <-

问题 I have a categorical scatter plot like this: which I generated in R with the following code (using the ggplot2 library): data <- runif(50, 13, 17) factors <- as.factor(sample(1:3, 50, replace = TRUE)) groups <- as.factor(sample(1:3, 50, replace = TRUE)) data_table <- data.frame(data, factors) g <- ggplot(data_table, aes(y = data_table[, 1], x = data_table[, 2], colour = groups)) + geom_point(size = 1.5) I am trying to add an average line for each x-group, but I can't manage to find the right

问题 I have county level data recording the year an invasive insect pest was first detected in that county between 2002 and 2018. I created a map using ggplot2 and the maps package that fills the county polygons with a color according to the year the pest was detected. **Is there a way to use the gganimate package to animate this map with the first frame filling in only polygons with a detection date of 2002, the second frame filling polygons with a detection date of 2003 or earlier (so 2002 and

问题 I have tried to read through stackoverflow, blogs, books etc but have been unable to find the answer on plotting time in the x-axis in the following format(HH:MM:SS.000) in R and another quantity on the y-axis. I have the following dataset: Time EcNo 12:54:09.000 -14.47 12:54:10.000 -17.96 12:54:11.000 -15.97 12:54:12.000 -14.61 12:54:13.000 -12.68 12:54:14.000 -10.73 12:54:15.000 -10.54 12:54:16.000 -11.62 12:54:17.000 -12.49 12:54:18.000 -11.12 How would I plot EcNo on Yaxis vs Time(x axis)

问题 I would like to plot a SpatialLinesDataFrame calling ggplot with function fortify . The problem I have when using fortify is that I get undesirable lines between my points. I think it has something to do with the plot order Here is an example of my data : Coords <- matrix(c(4095215,2303286,4095275,2303226,4095275,2303196,4095395,2303076, 4095425,2303076,4095485,2303016,4095485,2302896,4095545,2302836,4095545,2302806, 4095575,2302776,4095575,2302746,4095635,2302686,4095635,2302656,4095665

问题 In a attempt to make a test 2d density plot with ggplot2, I used the code snippet: ggplot(df, aes(x = S1.x, y = S1.y)) + geom_point() + geom_density_2d() and I got the error: "Computation failed in stat_density2d() : bandwidths must be strictly positive" My dataframe looks like this: > df transcriptID S1.x S1.y S2.x S2.y DQ459412 0.000000 0.000000 0.000000 0.000000 DQ459413 1.584963 2.358379 4.392317 3.085722 DQ459415 0.000000 0.000000 0.000000 0.000000 DQ459418 0.000000 0.000000 0.000000 0

问题 Below is a reproducible example of the issue I am trying to solve. I have created a heatmap of sorts in ggplot2 and things have been going well. Since I have put percentage signs on the data to use with geom_text I would like to make the legend of geom_tile also to display percent signs (I can only multiply the actual values by 100 right now). Ideally I would like the legend bar on the right to show 8%, 4%, 0%, -4%, -8%. #load in libraries require(plyr) require(dplyr) require(reshape2)
